Kilwa Kisiwani (Kilwa Island) is an island, national historic site, and hamlet community located in the township of Kilwa Masoko, the district seat of Kilwa District in the Tanzanian region of Lindi in southern Tanzania. Kilwa Kisiwani is the largest of the nine hamlets in the town of Kilwa Masoko and is also the least populated hamlet in the township with fewer than 1,000 residents.
At its peak in the Middle Ages, Kilwa had over 10,000 inhabitants. Since 1981, the entire island of Kilwa Kisiwani has been designated by UNESCO as a World Heritage Site along with the nearby ruins of Songo Mnara. Despite its significant historic reputation, Kilwa Kisiwani is still home to a small and resilient community of natives who have inhabited the island for centuries. Kilwa Kisiwani is one of the seven World Heritage Sites in Tanzania.[2] Additionally, the site is a registered National Historic Site of Tanzania.[3]
Geography
Kilwa Kisiwani Island lies 9 degrees south of the equator. The island is 23km (14mi) in circumference and the total land area is 12km2 (4.6sqmi). On the west part of the island is the Mavuji River estuary.[4] On the south part of the island lies the Sagarungu sound and to the east lies the Indian Ocean.

The island is located with the Kilwa Masoko township authority. The main economic activities on the island are cultural tourism, fishing and subsistence agriculture. Economic growth is limited due to the island's isolation. There no rivers and the main source for water is wells. Many of the island's freshwater wells have been used for over a millennium. The island is served by small boats to and from Kilwa Masoko. The island's only electricity is generated from solar power and has a small capacity. There are no roads on the island thus most transport is on foot or by motorcycle.
To protect the historic integrity of the island, non-island residents are strictly prohibited from visiting the island without a permit from the tourist information center in downtown Kilwa Masoko.[5] Much of the historical artifacts and buildings on the island have not yet been excavated.
Historical significance
Kilwa Kisiwani is an archaeological Swahilicity-state site located along the Swahili Coast on the Kilwa Archipelago. It was occupied (possibly) by the Mwera people from the mainland from at least the 8th century CE and eventually became one of the most powerful Swahili settlements along the East African coast. Historically, it was the center of the Kilwa Sultanate, a medieval Swahili sultanate whose authority at its height in the 13th, 14th and 15th centuries stretched the entire length of the Swahili Coast. The seasonal wind reversals affected trade.[6]
In 1331CE, Moroccan traveller and scholar Ibn Battuta visited Kilwa and described it as one of the beautiful cities of the world.[2] Trade connections with the Arabian Peninsula as well as India and China influenced the growth and development of Kilwa, and, though there are Islamic words and customs that have been adapted to the culture, the origins are African.[7] Many of the Swahili settlements showed complex layouts that reflected social relations between groups, however at Kilwa, there are many questions still left unanswered about the town's layout after the Portuguese burnt it to the ground in July 1505.[8]
The Swahili cemeteries are located on the edge of the town, which is common for the Swahili region, and large, open spaces were likely used for social gatherings.[9] An important city for trade, around the 13th century there were increased fortifications and a greater flow of goods. For these to take place, there would need to be a form of political administration overseeing the city, controlling the movement of goods. Much of the trade network was with the Arabian peninsula. Kilwa Kisiwani reached its highest point in wealth and commerce between the 13th and 15th centuries.[7]
Evidence of growth in wealth can be seen with the appearance of stone buildings around the 13th century, before which all of the buildings were wattle-and-daub. The socio-economic status of the individuals residing there can be inferred from the type of structure they were living in. Among Kilwa's trade exports were spices, tortoiseshell, coconut oil, ivory, and aromatic gums, as well as gold.[6] At around this time, Kilwa had seized control of the trade of gold at Sofala, Mozambique. The wealthier residents of Kilwa owned exotic textiles and foreign ceramics, though items such as luxury clothes are not preserved in the archaeological record.[7] For approximately 500 years, Kilwa minted its own coins. This lasted from about 1100-1600 CE and the coins have been found across the region, including Great Zimbabwe.[10]
Marine resources were abundant and used for food, supplemented by the surrounding land. Due to the impact the sea had on Kilwa, including marine resources and trade opportunities, the archaeological investigation of the harbors and ports is considered to be of high importance. The topsoil that covers the limestone at Kilwa was of poor quality, and so food sources on land came from the areas of higher ground. However, the soil in the Kilwa region would have been suitable for growing cotton, which could be used in sail manufacturing. Spindle whorls from the 12th century have been found, indicating that cotton was used and processed in this area.[7]
Ceramics
Kilwa pot sherds about 1000 to 1500.
At first, most of the focus was placed on the archaeology of Kilwa's ports and harbors, however, more and more emphasis is being placed on Kilwa's hinterlands. Ceramic artifacts are plentiful at the site and can be divided into two groups: regional and coastal. All of the ceramics with regional distribution were locally produced, but the area of distribution is limited. These unglazed ceramics were referred to as Kitchen Wares, though their uses were not necessarily just as cooking vessels. All of the varieties of locally produced pottery found in the region were also uncovered at the site of Kilwa itself.[11]
While the Kitchen Wares could be seen throughout the region, there were ceramics that were mostly seen within Kilwa itself. These included modeled forms and red-burnished wares. The distribution pattern of the red-burnished wares was coastal. Other ceramic types that were seemingly restricted to town were the imported ceramic vessels from the Arabian peninsula and China. Imported ceramic materials are not found in rural areas. They were used as a sign of social status by the elite. They were kept in wall niches made just for the purpose of displaying them. These imported ceramics played important symbolic roles along the Swahili Coast. The symbolism attached to the imported ceramics was so strong that it carried on to modern Swahili culture. The lack of imported goods in the hinterlands indicates that, while Kilwa was undergoing a process of urbanization, the other local communities did not undergo a dramatic transformation.[11]
Ancient DNA analysis
A study by Brielle et al. in 2023 completed ancient DNA analysis of several samples from the ruins of Kilwa. Ancient DNA (aDNA) analysis was completed for 80 individuals from six medieval and early modern (1250–1800 CE) coastal towns and an inland town after 1650 in order to determine the proportions of "African-like, Persian-like, and Indian-like" DNA sequences. More than half of the DNA of many of the individuals from coastal towns originated from primarily female ancestors from Africa, with a large proportion — sometimes more than half—of the DNA coming from Asian ancestors. The Asian ancestry includes components associated with Persia and India, with 80–90% of the Asian DNA originating from Persian men. Peoples of African and Asian (predominantly Persian) origins began to mix by about 1000 CE.[12] Samples were taken from two boxes of human remains located the in British Institute in Eastern Africa (BIEA) in Nairobi, originally excavated in the 1950s and 1960s by Chittick.[13]
After 1500, the sources of male Asian DNA became increasingly Arabian, consistent with increased interactions with southern Arabia. From medieval times until the modern day, subsequent interactions with different Asian and African people have changed the ancestry of the present-day people living on the Swahili coast compared to the medieval individuals whose DNA was sequenced.[12]
Potentially dating from 1300-1600 (more precise radiocarbon dating techniques were unable to be completed in time for these samples), analysis was completed of the individuals' mitochondrial DNA (mtDNA), autosomal DNA, Y chromosome DNA, and X chromosome DNA. Analysis of mtDNA in the individual, demonstrating maternal ancestry patterns, showed a L* haplotype. The L* haplotype is predominantly found in present-day Sub-Saharan African populations. Y chromosome analysis, demonstrating paternal ancestry patterns, showed that the individual was carrying the J2 haplotype, a DNA pattern found in Southwest Asian or Persian individuals. X chromosomes, containing larger maternal influence, were compared with the 22 autosomal chromosomes, which contain equal maternal and paternal influence. X chromosomes contained more indicators of African ancestry compared to the autosomal DNA, further adding to evidence of African ancestry on the maternal side and Persian or Southeast Asian ancestry on the paternal side.[12]
Preservation
In 2004, Kilwa Kisiwani was inscribed on UNESCO's List of World Heritage in Danger. There is a serious rapid deterioration of the archaeological and monumental heritage of these two islands due to various agents like erosion and vegetation. The eastern section of the Palace of Husuni Kubwa, for example, is progressively disappearing. The damage to the soil caused by rainwater wash is accentuating the risks of the collapse of the remaining structures on the edge of the cliff. The vegetation that proliferates on the cliff has limited the progression of the rain-wash effect but causes the break-up of the masonry structures. The World Monuments Fund included Kilwa on its 2008 Watch List of 100 Most Endangered Sites, and since 2008 has been supporting conservation work on various buildings. In 2014 it was removed from the list.[2]
Between 2005 and 2009, the Zamani Project documented some of the Swahili ruins on Kilwa Kisiwani with terrestrial 3D laser scanning.[14][15][16][17] The structures documented include: the Gereza (prison); the Great Mosque; the Husuni Kubwa; the Makutani Building and the Malindi Mosque. Some of the 3D models, a panorama tour, elevations, sections and plans are available on www.zamaniproject.org.
Historic buildings
Great Mosque
Great Mosque Kilwa Kisiwani, Kilwa Masoko Ward, Kilwa District, Lindi Region
Early construction
The earliest section, likely the northern prayer hall, dates back to the 12th century. Built between 1131 and 1170 (according to historical records[18][19].), this rectangular structure showcased typical construction of the period. The load-bearing walls were built with square coral limestone blocks, and three symmetrical entrances with vaulted ceilings provided access. Uniquely for mosques in the area, the flat roof was supported by nine hexagonal columns made from single tree trunks.[20][21]
Archaeological discoveries have shed light on the original design. The roof, constructed from coral tiles embedded in mortar, featured decorative concentric circles. Traces of red paint suggest the mosque may have been adorned in red and black, adding a touch of color.[22]
Later additions and renovations
The early 14th century saw a major expansion under Sultan al-Hasan ibn Sulaiman, who also constructed the nearby Palace of Husuni Kubwa. This extension likely included the grand dome described by Ibn Battuta during his visit in 1331.
The mihrab, the niche indicating the direction of prayer, appears to be a later addition.[23] Its design – a pointed arch, capitals, pilasters, friezes, and a fluted half-dome vault – differs from the original structure. Interestingly, protruding coral blocks suggest the presence of a fixed wooden minbar, and traces of oblong niches within the main niche hint at a possible Shirazi influence. These elements may have been incorporated from an earlier design during renovations.
Water management system
The western section of the mosque housed the ablution area, essential for worshippers to perform ritual cleansing before prayers. Restoration efforts unearthed an intricate network of water channels made from baked clay, providing insights into the mosque's well-designed water management system.
Palace of Husuni Kubwa
Palace in Kilwa Kisiwani of Kilwa Masoko Ward, Kilwa District, Lindi Region, UNESCO WHS
Husuni Kubwa (the "Great Palace"), situated outside the town, was an early 14th-century sultan's palace and emporium. Other defining features include causeways and platforms at the entrance of the Harbour made from blocks of reef and coral nearly a meter high. These act as breakwaters, allowing mangroves to grow which is one of the ways the breakwater can be spotted from a distance. Some parts of the causeway are made from the bedrock, but usually the bedrock was used as a base. Coral stone was used to build up the causeways with sand and lime being used to cement the cobbles together. Some of the stones were left loose.[24]
The Palace of Husuni Kubwa is another prominent structure in Kilwa. The majority of the palace was erected in the 14th century by Sultan al-Hasan ibn Sulaiman, who also built an extension to the nearby Great Mosque of Kilwa, although portions may date back to the 13th century. for unknown reasons, the palace was inhabited only for a brief period of time, and abandoned before its completion.
In true Swahili architecture style the structure was built out of coral stone on a high bluff overlooking the Indian Ocean. It consists of three major elements: a south court, used primarily for commerce; a residential complex including over one hundred individual rooms; and a wide stairway leading down to a mosque on the beach.
Other notable features include a pavilion, which likely served as a reception hall, and an octagonal swimming pool. All of Husuni Kubwa spans across approximately two acres. The coral rag was set in limestone mortar and cut stone was used for decorative pieces, door jams, and vaults. The rooms were about 3 meters tall. The roof was made from cut limestone blocks laid across cut timbers and the floors were white plaster. The main entrance to Husuni Kubwa is from the shore.
Interior of Small Mosque in Kilwa Kisiwani of Kilwa Masoko Ward, Kilwa District, Lindi Region
Most of the imported glazed pottery recovered at the site was Chinese celadon, though there were a few Ying Ch'ing stoneware sherds present, and a Yuan dynasty flask dated to about 1300 CE. Neither the Kilwa Chronicle nor any other Portuguese accounts describe a building comparable to Husuni Kubwa.[25]

Husuni Ndogo
Husuni Ndogo ("Little Palace") is built from coral rubble and limestone mortar. The rectangular enclosure wall surrounds the complex and at each corner stands a tower. The foundations extend two meters below ground level. It appears to have been built as a fort, but the exact purposes and uses are somewhat unknown. There is some evidence that it, for at least a time, was used as a mosque. Architecturally, it appears to be different from other buildings along the coast, resembling buildings constructed under the Caliphs of the Umayyad at around 661-750 CE. However, whether or not the structure is related or even dates to the Arabic buildings remains uncertain, though it seems unlikely.[25]

Gereza Fort
Gerezani, Kilwa Kisiwani, Kilwa Masoko Ward, Kilwa District, Lindi Region
The Gereza Fort (also called the Arab Fort)[26] is situated between the Makutani Palace and the Great Mosque. There are some evidence that the original structure was Portuguese, while the present form of the fort is of typical Omani forts.[27] The word Gereza means prison in Swahili, possibly indicating the use of the fort as an Omani slave holding building during the late 18th century to late 19th century after the collapse of the Swahili civilization after the arrival of the Portuguese in late 16th century.[28]

A lot of Kilwa's history has been written by Omani and European colonial administrators in the 19th century. There has been a lot of contradictory evidence on the origins and the role of foreign immigrants in Kilwa's history.[29]Historians John Thornton and Linda Heywood of Boston University have estimated that of the Africans captured and then sold as slaves, around 90% were enslaved by fellow Africans who sold them to foreign traders. Slavery was ended because of British intervention in Zanzibar.[citation needed]
According to local oral tradition, in the 11th century the island of Kilwa Kisiwani was sold to Ali bin Hasan, son of the "King" of Shiraz, in Persia. Another tradition relates that his mother was Somali.[citation needed] Ali bin Al-Hasan is credited with founding the island city and with marrying the daughter of the local king. Though he was credited with the founding, he had arrived at an already inhabited area. He did, however, come to power and is credited with fortifying the city and increasing trade.[6] Tradition also relates that it was the child of this union who founded the Kilwa Sultanate. Archaeological and documentary research has revealed that over the next few centuries, Kilwa grew to be a substantial city and the leading commercial entrepôt on the southern half of the Swahili Coast (roughly from the present Tanzanian-Kenya border southward to the mouth of the Zambezi River), trading extensively with states of the Southeast African hinterland as far as Zimbabwe. Trade was mainly in gold, iron, ivory and other animal products of the interior for beads, textiles, jewelry, porcelain and spices from Asia. On the contrary, there is no evidence of Shirazi-based Shia Islam in Kilwa and the entire East African coast.[29]
By the 12th century, under the rule of the Abu'-Mawahib dynasty, Kilwa had become the most powerful city on the Swahili Coast. At the zenith of its power in the 15th century, the Kilwa Sultanate claimed authority over the city-states of Malindi, Mvita (Mombasa), Pemba Island, Zanzibar, Mafia Island, Comoro, Sofala and the trading posts across the channel on Madagascar.
Ibn Battuta recorded his visit to the city around 1331, and commented favorably on the generosity, humility, and religion of its ruler, Sultan al-Hasan ibn Sulaiman. Ibn Battuta also describes how the sultan would go into the interior and raid the people taking slaves and other forms of wealth. He was also particularly impressed by the planning of the city and believed that it was the reason for Kilwa's success along the coast.[30] From this period, the construction of the Palace of Husuni Kubwa and a significant extension to the Great Mosque of Kilwa, which was made of coral stones, the largest mosque of its kind. Kilwa was an important and wealthy city for the trade of gold. Because of trade, some of the people who lived in Kilwa had a higher standard of living, but many others were poor. The wealthy enjoyed indoor plumbing in their stone homes and the poor lived in mud huts with thatched roofs.[31]
In the early 16th century, Vasco da Gama extorted tribute from the wealthy Islamic state. In 1505 another Portuguese force commanded by D. Francisco de Almeida took control of the island after besieging it. It remained in Portuguese hands until 1512, when an Arab mercenary captured Kilwa after the Portuguese abandoned their outpost [citation needed]. The city regained some of its earlier prosperity, but in 1784 was conquered by the Omani rulers of Zanzibar.[citation needed] In 1776, king of Kilwa signed a treaty with a French merchant to deliver 1,000 slaves per year at twenty piastres each and two piastres as a present to the king.[32] After the Omani conquest, the French built and manned a fort at the northern tip of the island, but the city itself was abandoned in the 1840s. It was later part of the colony of German East Africa from 1886 to 1918.
Health and education
Since the resident island population is less than 1000 people, there is one school, the Lyahi Koranic Middle school. Older students move to the mainland for further education. There are no healthcare facilities on the island so residents have to take the boat to the mainland to receive healthcare services at either the Masoka Urban Health Center or the Masoko BAKWATA Dispensary both in Kilwa Masoko.[33]
The ruins of Gedi are a historical and archaeological site near the Indian Ocean coast of eastern Kenya. The site is adjacent to the town of Gedi in the Kilifi District and within the Arabuko-Sokoke Forest.
The Swahili people comprise mainly Bantu, Afro-Arab and Comorian ethnic groups inhabiting the Swahili coast, an area encompassing the Zanzibar archipelago and mainland Tanzania's seaboard, littoral Kenya, northern Mozambique, the Comoros Islands and Northwest Madagascar.
Zanj was a name used by medieval Muslim geographers to refer to both a certain portion of Southeast Africa and to its Bantu inhabitants. This word is also the origin of the place-names Zanzibar and the Sea of Zanj.
Kilwa District is one of six administrative districts of Lindi Region in Tanzania. The District covers an area of 15,000 km2 (5,800 sq mi). The district is comparable in size to the land area of the nation state of East Timor. Kilwa district is bordered to the north by Rufiji District in Pwani Region, to the east by the Indian Ocean, to the south by the Lindi District, Nachingwea District together with Ruangwa District, and to the west by the Liwale District. The district borders every other district in Lindi Region except Lindi Municipal District. The district seat (capital) is the town of Kilwa Masoko. The district is named after the medieval Swahili city state of Kilwa Kisiwani. According to the 2012 census, the district has a total population of 190,744. By 2022, the population had increased to 297,676.
Kilwa Masoko or Masoko is an administrative ward in Kilwa District of Lindi Region in Tanzania. The ward covers an area of 200 km2 (77 sq mi), and has an average elevation of 11 m (36 ft). The ward is also the capital of Kilwa District. According to the 2012 census, the ward has a total population of 13,601.
The Tongoni Ruins are a 15th century Swahili ruins of a mosque and forty tombs located in Tongoni ward in Tanga District inside Tanga Region of Tanzania. The largest and possibly most significant Swahili site in Tanzania is Tongoni, which is located 25 km north of the Pangani River. Overlooking Mtangata Bay, about forty standing tombs and a Friday mosque of the "northern" style occupy a third of a hectare. People from the area continue to worship there spiritually. They bury their departed family members to the south of the historic tombs. The area was a different place four to five centuries ago. Contrary to its almost unnoticed presence today, it was a prosperous and a respected Swahili trading centre during the 15th century. Most of the ruins are still not yet been uncovered. The site is a registered National Historic Site.
Mikindani is a historic coastal town located in Mtwara-Mikindani District of Mtwara Region in Tanzania. The name comes from the Swahili word mikinda which means "young coconut trees". Therefore the term "Mikindani', literally means "the place where there are young coconut trees" in old Swahili language. Mikindani is part of the city of Mtwara and is governed by the Mtwara Mikindani Municipal Council. The site is a registered National Historic Site.
Swahili architecture is a term used to designate a whole range of diverse building traditions practiced or once practiced along the eastern and southeastern coasts of Africa. Rather than simple derivatives of Islamic architecture from the Arabic world, Swahili stone architecture is a distinct local product as a result of evolving social and religious traditions, environmental changes, and urban development.
The Great Mosque of Kilwa is a congregational mosque on the island of Kilwa Kisiwani, in Kilwa Masoko in Kilwa District in Lindi Region of Tanzania. It was likely founded in the tenth century, but the two major stages of construction date to the eleventh or twelfth and thirteenth century, respectively. It is one of the earliest surviving mosques on the Swahili coast and is one of the first mosques built without a courtyard.
Sultan al-Hasan ibn Sulaiman, often referred to as "Abu'l-Muwahib", was a ruler of Kilwa Kisiwani, in present-day Tanzania, from 1310 until 1333. His full name was Abu al-Muzaffar Hasan Abu al-Muwahib ibn Sulaiman al-Mat'un ibn Hasan ibn Talut al-Mahdal.
Dr. Neville H. Chittick was a British scholar and archaeologist. He specialized in the historic cultures of Northeast Africa, and also devoted various works to the Swahili Coast.
Pangani is a historic town and capital of Pangani District in the Tanga Region of Tanzania. The town lies 45 km (28 mi) south of the city of Tanga, at the mouth of the Pangani River in which the town is named after. Administrately the town Pangani is situated within two wards, Pangani Mashariki and Pangani Magharibi. The town is currently the largest settlement in Pangani District and is a major tourist attraction in Tanga region and is a home to Muhembo, a Tanzanian National Historic Site.
The Swahili coast is a coastal area of East Africa, bordered by the Indian Ocean and inhabited by the Swahili people. It includes Sofala ; Mombasa, Gede, Pate Island, Lamu, and Malindi ; and Dar es Salaam and Kilwa. In addition, several coastal islands are included in the Swahili coast, such as Zanzibar and Comoros.
The Shirazi also known as Mbwera, are a Bantu ethnic group inhabiting the Swahili coast and the nearby Indian ocean islands. They are particularly concentrated on the islands of Zanzibar, Pemba and Comoros.
Songo Mnara is a historic Swahiili settlement in located on Songo Mnara Island in Pande Mikoma, Kilwa District in Lindi Region of Tanzania. The island is home to a Medieval Swahili stone town. The stone town was occupied from the 14th to 16th centuries. Songo Mnara has been recognized as a UNESCO World Heritage Site, along with nearby stone town Kilwa Kisiwani. In total, archaeologists have found six mosques, four cemeteries, and two dozen house blocks along with three enclosed open spaces on the island. Songo Mnara was constructed from rough-coral and mortar. This stonetown was built as one of many trade towns on the Indian Ocean. The site is a registered National Historic Site.
Pemba Island is a large coral island off the coast of Tanzania. Inhabited by Bantu settlers from the Tanga coast since 600 AD, the island has a rich trading, agricultural, and religious history that has contributed to the studies of the Swahili Coast trade throughout the Indian Ocean.
