A citadel is the most fortified area of a town or city. It may be a castle, fortress, or fortified center. The term is a diminutive of city, meaning "little city", because it is a smaller part of the city of which it is the defensive core.
In a fortification with bastions, the citadel is the strongest part of the system, sometimes well inside the outer walls and bastions, but often forming part of the outer wall for the sake of economy. It is positioned to be the last line of defence, should the enemy breach the other components of the fortification system. [1]
Some of the oldest known structures which have served as citadels were built by the Indus Valley civilisation, where citadels represented a centralised authority. Citadels in Indus Valley were almost 12 meters tall. [2] The purpose of these structures, however, remains debated. Though the structures found in the ruins of Mohenjo-daro were walled, it is far from clear that these structures were defensive against enemy attacks. Rather, they may have been built to divert flood waters.
Several settlements in Anatolia, including the Assyrian city of Kaneš in modern-day Kültepe, featured citadels. Kaneš' citadel contained the city's palace, temples, and official buildings. [3] The citadel of the Greek city of Mycenae was built atop a highly-defensible rectangular hill and was later surrounded by walls in order to increase its defensive capabilities. [4]
In Ancient Greece, the Acropolis, which literally means "high city", placed on a commanding eminence, was important in the life of the people, serving as a lookout, a refuge, and a stronghold in peril, as well as containing military and food supplies, the shrine of the god and a royal palace. The most well known is the Acropolis of Athens, but nearly every Greek city-state had one – the Acrocorinth famed as a particularly strong fortress. In a much later period, when Greece was ruled by the Latin Empire, the same strong points were used by the new feudal rulers for much the same purpose.
In the first millennium BC, the Castro culture emerged in northwestern Portugal and Spain in the region extending from the Douro river up to the Minho, but soon expanding north along the coast, and east following the river valleys. It was an autochthonous evolution of Atlantic Bronze Age communities. In 2008, the origins of the Celts were attributed to this period by John T. Koch [5] and supported by Barry Cunliffe. [6] The Ave River Valley in Portugal was the core region of this culture, [7] with a large number of small settlements (the castros), but also settlements known as citadels or oppida by the Roman conquerors. These had several rings of walls and the Roman conquest of the citadels of Abobriga, Lambriaca and Cinania around 138 BC was possible only by prolonged siege. [8] Ruins of notable citadels still exist, and are known by archaeologists as Citânia de Briteiros, Citânia de Sanfins, Cividade de Terroso and Cividade de Bagunte. [7]
Rebels who took power in a city, but with the citadel still held by the former rulers, could by no means regard their tenure of power as secure. One such incident played an important part in the history of the Maccabean Revolt against the Seleucid Empire. The Hellenistic garrison of Jerusalem and local supporters of the Seleucids held out for many years in the Acra citadel, making Maccabean rule in the rest of Jerusalem precarious. When finally gaining possession of the place, the Maccabeans pointedly destroyed and razed the Acra, though they constructed another citadel for their own use in a different part of Jerusalem.
At various periods, and particularly during the Middle Ages and the Renaissance, the citadel – having its own fortifications, independent of the city walls – was the last defence of a besieged army, often held after the town had been conquered. Locals and defending armies have often held out citadels long after the city had fallen. For example, in the 1543 Siege of Nice the Ottoman forces led by Barbarossa conquered and pillaged the town and took many captives, but the citadel held out.
In the Philippines, the Ivatan people of the northern islands of Batanes often built fortifications to protect themselves during times of war. They built their so-called idjangs on hills and elevated areas. These fortifications were likened to European castles because of their purpose. Usually, the only entrance to the castles would be via rope ladder that would only be lowered for the villagers and could be kept away when invaders arrived. [9]
In times of war, the citadel in many cases afforded retreat to the people living in the areas around the town. However, citadels were often used also to protect a garrison or political power from the inhabitants of the town where it was located, being designed to ensure loyalty from the town that they defended. This was used, for example, during the Dutch Wars of 1664–1667, King Charles II of England constructed a Royal Citadel at Plymouth, an important channel port which needed to be defended from a possible naval attack. However, due to Plymouth's support for the Parliamentarians, in the then-recent English Civil War, the Plymouth Citadel was so designed that its guns could fire on the town as well as on the sea approaches.
Barcelona had a great citadel built in 1714 to intimidate the Catalans against repeating their mid-17th- and early-18th-century rebellions against the Spanish central government. [10] In the 19th century, when the political climate had liberalized enough to permit it, the people of Barcelona had the citadel torn down, and replaced it with the city's main central park, the Parc de la Ciutadella. [11] A similar example is the Citadella in Budapest, Hungary.
The attack on the Bastille in the French Revolution – though afterwards remembered mainly for the release of the handful of prisoners incarcerated there – was to considerable degree motivated by the structure's being a Royal citadel in the midst of revolutionary Paris.
Similarly, after Garibaldi's overthrow of Bourbon rule in Palermo, during the 1860 Unification of Italy, Palermo's Castellamare Citadel – a symbol of the hated and oppressive former rule – was ceremoniously demolished.
Following Belgium gaining its independence in 1830, a Dutch garrison under General David Hendrik Chassé held out in Antwerp Citadel between 1830 and 1832, while the city had already become part of independent Belgium.
The Siege of the Alcázar in the Spanish Civil War, in which the Nationalists held out against a much larger Republican force for two months until relieved, shows that in some cases a citadel can be effective even in modern warfare; a similar case is the Battle of Huế during the Vietnam War, where a North Vietnamese Army division held the citadel of Huế for 26 days against roughly their own numbers of much better-equipped US and South Vietnamese troops.
The Citadelle of Québec (the construction was started in 1673 and completed in 1820) still survives as the largest citadel still in official military operation in North America. It is home to the Royal 22nd Regiment of the Canadian Army [12] and forms part of the Ramparts of Quebec City dating back to 1620s. [13]
Since the mid 20th century, citadels have commonly enclosed military command and control centres, rather than cities or strategic points of defence on the boundaries of a country. These modern citadels are built to protect the command centre from heavy attacks, such as aerial or nuclear bombardment. The military citadels under London in the UK, including the massive underground complex Pindar beneath the Ministry of Defence, are examples, as is the Cheyenne Mountain nuclear bunker in the US.
On armoured warships, the heavily armoured section of the ship that protects the ammunition and machinery spaces is called the armoured citadel.
A modern naval interpretation refers to the heaviest protected part of the hull as "the vitals", and the citadel is the semi-armoured freeboard above the vitals. Generally, Anglo-American and German languages follow this while Russian sources/language refer to "the vitals" as цитадель "citadel". Likewise, Russian literature often refers to the turret of a tank as the 'tower'.
The safe room on a ship is also called a citadel.
An acropolis was the settlement of an upper part of an ancient Greek city, especially a citadel, and frequently a hill with precipitous sides, mainly chosen for purposes of defense. The term is typically used to refer to the Acropolis of Athens, yet every Greek city had an acropolis of its own. Acropolises were used as religious centers and places of worship, forts, and places in which the royal and high-status resided. Acropolises became the nuclei of large cities of classical ancient times, and served as important centers of a community. Some well-known acropolises have become the centers of tourism in present-day, and, especially, the Acropolis of Athens has been a revolutionary center for the studies of ancient Greece since the Mycenaean period. Many of them have become a source of revenue for Greece, and represent some great technology during the period.
The Acropolis of Athens is an ancient citadel located on a rocky outcrop above the city of Athens, Greece, and contains the remains of several ancient buildings of great architectural and historical significance, the most famous being the Parthenon. The word Acropolis is from the Greek words ἄκρον and πόλις. The term acropolis is generic and there are many other acropoleis in Greece. During ancient times the Acropolis of Athens was also more properly known as Cecropia, after the legendary serpent-man Cecrops, the supposed first Athenian king.
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or by well-prepared assault. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy.
A defensive wall is a fortification usually used to protect a city, town or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications with towers, bastions and gates for access to the city. From ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as letzis were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls also had important symbolic functions – representing the status and independence of the communities they embraced.
A fortification is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere.
Lindos is an archaeological site, a fishing village and a former municipality on the island of Rhodes, in the Dodecanese, Greece. Since the 2011 local government reform it is part of the municipality Rhodes, of which it is a municipal unit. The municipal unit has an area of 178.9 km2. It lies on the east coast of the island. It is about 40 km south of the city of Rhodes and its fine beaches make it a popular tourist and holiday destination. Lindos is situated in a large bay and faces the fishing village and small resort of Charaki.
The Bracari or Callaeci Bracari were an ancient Celtic tribe of Gallaecia, living in the northwest of modern Portugal, in the province of Minho, between the rivers Tâmega and Cávado. After the conquest of the region beginning in 136BC, the Romans established the Augustan citadel of Bracara, modern Braga, in 20 BC.
The Citadelle Laferrière, commonly known as La Citadelle, is a large early 19th-century fortress located in Milot in Nord, Haiti. It is situated on the Bonnet à l'Evêque mountaintop located approximately 8 kilometres (5.0 mi) uphill from the town of Milot, 27 kilometres (17 mi) south of the city of Cap-Haïtien, and 15 kilometres (9.3 mi) southwest of the Three Bays Protected Area.
Castro culture is the archaeological term for the material culture of the northwestern regions of the Iberian Peninsula from the end of the Bronze Age until it was subsumed by Roman culture. It is the culture associated with the Gallaecians and Astures.
Cividade de Terroso was an ancient city of the Castro culture in North-western coast of the Iberian Peninsula, situated near the present bed of the Ave river, in the suburbs of present-day Póvoa de Varzim, Portugal.
The Acra, with the meaning of "stronghold", was a place in Jerusalem thought to have had a fortified compound built by Antiochus Epiphanes, ruler of the Seleucid Empire, following his sack of the city in 168 BCE. The name Acra was also used at a later time for a city quarter probably associated with the by-then destroyed fortress, known in his time to Josephus as both Acra and "the lower city". The fortress played a significant role in the events surrounding the Maccabean Revolt, which resulted in the formation of the Hasmonean Kingdom. The "upper city" was captured by Judas Maccabeus, with the Seleucid garrison taking refuge in the "Acra" below, and the task of destroying this last enemy stronghold inside Jerusalem fell to Simon Maccabeus surnamed Thassi. Our knowledge about the Acra is based almost exclusively on the writings of Josephus, which are of a later date, and on the First and Second Books of Maccabees, which were written not long after the described events.
Cividade Hill or Cividade de Terroso Hill with an elevation of 153 metres (502 ft) is one of the two hills next to the city of Póvoa de Varzim in Portugal.
Harappan architecture is the architecture of the Bronze Age Indus Valley civilization, an ancient society of people who lived during c. 3300 BCE to 1300 BCE in the Indus Valley of modern-day Pakistan and India.
The ramparts of Quebec City is a city wall that surrounds the western end of Old Quebec's Upper Town in Quebec City, Quebec, Canada. The ramparts date back to the 17th century, with the ramparts having undergone a succession of modifications and improvements throughout their history. The city walls extend 4.6 kilometres (2.9 mi), with the southern portions of the ramparts forming a part of the Citadelle of Quebec.
The Citânia de Briteiros is an archaeological site of the Castro culture located in the Portuguese civil parish of Briteiros São Salvador e Briteiros Santa Leocádia in the municipality of Guimarães; important for its size, "urban" form and developed architecture, it is one of the more excavated sites in northwestern Iberian Peninsula. Although primarily known as the remains of an Iron Age proto-urban hill fort, the excavations at the site have revealed evidence of sequential settlement, extending from the Bronze to Middle Ages.
The Castello di Milazzo is a castle and citadel in Milazzo, Sicily. It is located on the summit of a hill overlooking the town, on a site first fortified in the Neolithic era. The Greeks modified it into an acropolis, and it was later enlarged into a castrum by the Romans and Byzantines. The Normans built a castle, which was further modified and enlarged during the Medieval and Early Modern periods. It is now in good condition, and open to the public.
The Ptolemaic Baris was a citadel maintained by Ptolemaic Egypt during its rule of Jerusalem in the 3rd century BC. Described by only a few ancient sources, no archaeological remains of the citadel have been found and much about it remains a matter of conjecture.
The Heptapyrgion, modern Eptapyrgio, also popularly known by its Ottoman Turkish name Yedi Kule, is a Byzantine and Ottoman-era fortress situated on the north-eastern corner of the Acropolis of Thessaloniki in Greece. Despite its name, which in both languages means "Fortress of Seven Towers", it features ten, and was probably named after the Yedikule Fortress in Constantinople. It served as the major redoubt of the city's acropolis, as well as the seat of its garrison commander in Ottoman times, until the late 19th century. It was then converted to a prison, which remained open until 1989. References to the infamous Yedi Kule prison abound in the Greek rebetika songs. Restoration and archaeological work began in the 1970s and continues to this day.
The Walls of Trabzon are a series of defensive walls surrounding the old town of the city of Trabzon, northeastern Turkey. The fortifications are sometimes called the Trabzon Castle. However, they did not function as a castle, rather as city walls. Constructed on foundations dating back to the Roman era with cut stones from former structures at site, the walls stretch from the hill on the backside of the old town to the Black Sea shore. The walls further divided the city into three parts; the Upper Town or "fortress", the Middle Town and the Lower Town. The upper and middle towns are flanked by steep ravines cut by the Zagnos (Iskeleboz) and Tabakhane (Kuzgun) streams to the west and east respectively, while the lower town extends to the west of Zagnos.
