List of pre-Columbian engineering projects in the Americas

Last updated

Engineering in the Americas before the arrival of Christopher Columbus was advanced in agriculture, hydrology, irrigation systems, transportation, mechanical engineering, civil engineering and astronomy. In addition Native Americans made extensive use of fire to change the landscape and to create open areas for farming and hunting. Examples of pre-Columbian engineering from different indigenous civilizations can be found across North and South America.

<span class="mw-page-title-main">Pre-Columbian era</span> The Americas prior to European influences

In the history of the Americas, the pre-Columbian era spans from the original settlement of North and South America in the Upper Paleolithic period through European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures.

La Libertad is a region in northwestern Peru. Formerly it was known as the Department of La Libertad. It is bordered by the Lambayeque, Cajamarca and Amazonas regions on the north, the San Martín Region on the east, the Ancash and Huánuco regions on the south and the Pacific Ocean on the west. Its capital is Trujillo, which is the nation's third biggest city. The region's main port is Salaverry, one of Peru's largest ports. The name of the region is Spanish for "freedom" or "liberty"; it was named in honor of the Intendencia of Trujillo's proclaiming independence from Spain in 1820 and fighting for that. It is the ninth smallest department in Peru, but it is also its second-most populous department after Piura and its second-most densely populated department after Lambayeque.

Chimor was the political grouping of the Chimú culture. The culture arose about 900 CE, succeeding the Moche culture, and was later conquered by the Inca emperor Topa Inca Yupanqui around 1470, fifty years before the arrival of the Spanish in the region. Chimor was the largest kingdom in the Late Intermediate Period, encompassing 1,000 kilometres (620 mi) of coastline.

<span class="mw-page-title-main">Pre-Columbian art</span> Art of the Pre-Columbian civilizations

Pre-Columbian art refers to the visual arts of indigenous peoples of the Caribbean, North, Central, and South Americas from at least 13,000 BCE to the European conquests starting in the late 15th and early 16th centuries. The Pre-Columbian era continued for a time after these in many places, or had a transitional phase afterwards. Many types of perishable artifacts that were no doubt once very common, such as woven textiles, typically have not been preserved, but Precolumbian monumental sculpture, metalwork in gold, pottery, and painting on ceramics, walls, and rocks have survived more frequently.

<span class="mw-page-title-main">Chincha culture</span> Native American culture

The Chincha culture was the culture of a Native Peruvian people living near the Pacific Ocean in south west Peru. The Chincha Kingdom and their culture flourished in the Late Intermediate Period, also known as the regional states period of pre-Columbian Peru. They became part of the Inca Empire around 1480. They were prominent as sea-going traders and lived in a large and fertile oasis valley. La Centinela is an archaeological ruin associated with the Chincha. It is located near the present-day city of Chincha Alta.

Peruvian territory was inhabited 14,000 years ago by hunters and gatherers. Subsequent developments include the appearance of sedentary communities that developed agriculture and irrigation, and the emergence of complex socio-political hierarchies that created sophisticated civilizations, technology and monumental construction.

Paul August Kosok, was an American professor of history and government, who is credited as the first serious researcher of the Nazca Lines in Peru. His work on the lines started in 1939, when he was doing field study related to the irrigation systems of ancient cultures. By the 1950s, he had completed extensive mapping of more than 300 ancient canals in Peru, in collaboration with archeologist Richard P. Schaedel. Kosok demonstrated the culture's sophisticated management of water to support their settlements.

<span class="mw-page-title-main">Andén</span> Agricultural terraces in the Andes

An andén, Spanish for "platform", is a stair-step like terrace dug into the slope of a hillside for agricultural purposes. The term is most often used to refer to the terraces built by pre-Columbian cultures in the Andes mountains of South America. Andenes had several functions, the most important of which was to increase the amount of cultivatable land available to farmers by leveling a planting area for crops. The best known andenes are in Peru, especially in the Sacred Valley near the Inca capital of Cuzco and in the Colca Canyon. Many andenes have survived for more than 500 years and are still in use by farmers throughout the region.

Peruvian architecture is the architecture carried out during any time in what is now Peru, and by Peruvian architects worldwide. Its diversity and long history spans from ancient Peru, the Inca Empire, Colonial Peru to the present day.

<span class="mw-page-title-main">Puquios</span> Underground aqueducts in Peru and Chile

Puquios are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in the coastal deserts of southern Peru, especially in the Nazca region, and northern Chile. Forty-three puquios in the Nazca region were still in use in the early 21st century and relied upon to bring fresh water for irrigation and domestic use into desert settlements. The origin and dating of the Nazca puquios is disputed, although some archaeologists have estimated that their construction began about 500 CE by indigenous people of the Nazca culture.

<span class="mw-page-title-main">Andean civilizations</span> Civilizations of South Americas Andes Mountains

The Andean civilizations were complex societies of many cultures and peoples mainly developed in the river valleys of the coastal deserts of Peru. They stretched from the Andes of southern Colombia southward down the Andes to Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of Peru is the oldest known civilization in the Americas, dating back to 3200 BCE.

<span class="mw-page-title-main">History of Andean South America</span>

The history of human habitation in the Andean region of South America stretches from circa 15,000 BCE to the present day. Stretching for 7,000 km (4,300 mi) long, the region encompasses mountainous, tropical and desert environments. This colonisation and habitation of the region has been affected by its unique geography and climate, leading to the development of unique cultural and socn.

Ancient American Engineering refers to early American applied scientific and mathematical knowledge used to design and build structures, machines, devices, systems and material prior to the arrival and influence of Western and Eastern Civilizations. This knowledge belonged to the Aztecs, Incas, Mayans, and Anasazi, and covered two continents.

<span class="mw-page-title-main">Aqueduct (water supply)</span> Structure constructed to convey water

An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.

<span class="mw-page-title-main">Llanos de Moxos (archaeology)</span> Archaeological site in Bolivia

The Llanos de Moxos, also known as the Llanos de Mojos and the Beni Savanna, have extensive remains of pre-Columbian agricultural societies scattered over most of Beni Department, Bolivia. The remains testify to a well-organized and numerous indigenous people. This contradicts the traditional view of archaeologists, notably Betty Meggers, who asserted that the Amazon River Basin was not environmentally able to sustain a large population and that its indigenous inhabitants were hunter-gatherer bands or slash-and-burn farmers. In the 1960s, petroleum company geologists and geographer William Denevan were among the first to publicize the existence of extensive prehistoric earthworks constructed in the Amazon, especially in the Llanos de Moxos.

Huayuri, also called the Lost City of Huayuri, is a large pre-Columbian archaeological site which flourished from 1150 to 1450 CE in the Late Intermediate Period of Peru. Huayuri is located in the Peruvian coastal desert in Ica Region. Its prominence was probably dependent upon an climatic phase in which the area received greater precipitation than at earlier and later periods. The site may have been abandoned in the 16th century because of water shortages, conflict with the expanding Inca Empire, or epidemics of European diseases. The town of stone houses was located in a ravine between two mountain ridges, a location possibly dictated by a need for defense. Archaeological evidence indicates Huayari relied upon rainfall harvesting for its drinking water and some of the irrigated agriculture the town needed for the subsistence of the inhabitants.
