The Cahokia Mounds State Historic Site /kəˈhoʊkiə/ (11 MS 2)[2] is the site of a pre-Columbian Native American city (which existed c. 1050–1350 CE[3]) directly across the Mississippi River from present-day St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis and Collinsville.[4] The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km2), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km2), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.[5][a]
Cahokia was the largest and most influential urban settlement of the
Cahokia Mounds is a National Historic Landmark and a designated site for state protection. It is also one of the 25 UNESCO World Heritage Sites within the United States. The largest prehistoric earthen construction in the Americas north of Mexico,[5] the site is open to the public and administered by the Illinois Historic Preservation Division and supported by the Cahokia Mounds Museum Society. In celebration of the 2018 Illinois state bicentennial, the Cahokia Mounds were selected as one of the Illinois 200 Great Places[8] by the American Institute of Architects Illinois component (AIA Illinois). It was recognized by USA Today Travel magazine, as one of the selections for 'Illinois 25 Must See Places'.[9]
History
Development (9th and 10th centuries)
Although some evidence exists of occupation during the
The city's complex construction of earthen mounds required digging, excavation and transportation by hand using woven baskets. Construction made use of 55 million cubic feet (1.6 million cubic meters) of earth, and much of the work was accomplished over decades. Its highly planned large, smoothed-flat, ceremonial plazas, sited around the mounds, with homes for thousands connected by laid out pathways and courtyards, suggest the location served as a central religious pilgrimage city.[13]
The city's original name is unknown. The mounds were later named after the
Historian
Rise and peak (11th and 12th centuries)
Cahokia became the most important center for the
shells.Mill Creek chert, most notably, was used in the production of hoes, a high demand tool for farmers around Cahokia and other Mississippian centers. Cahokia's control of the manufacture and distribution of these hand tools was an important economic activity that allowed the city to thrive.[19] Mississippian culture pottery and stone tools in the Cahokian style were found at the Silvernale site[20] near Red Wing, Minnesota, and materials and trade goods from Pennsylvania, the Gulf Coast, and Lake Superior have been excavated at Cahokia.[21]
At the high point of its development, Cahokia was the largest urban center north of the great Mesoamerican cities in Mexico and Central America. Home to about 1,000 people before circa 1050, its population grew rapidly after that date. According to a 2007 study in Quaternary Science Reviews, "Between AD 1050 and 1100, Cahokia's population increased from between 1,400 and 2,800 people to between 10,200 and 15,300 people",[22] an estimate that applies only to a 1.8-square-kilometre (0.69 sq mi) high-density central occupation area.[23] Archaeologists estimate the city's population at between 6,000 and 40,000 at its peak,[24] with more people living in outlying farming villages that supplied the main urban center.
As a result of archeological excavations in the early 21st century, new residential areas were found to the west of Cahokia; this discovery increased estimates of historic area population.[24] If the highest population estimates are correct, Cahokia was larger than any subsequent city in the United States until the 1780s, when Philadelphia's population grew beyond 40,000.[25] Its population may have been larger than contemporaneous London[26] and Paris.[27]
One of the major problems that large centers like Cahokia faced was keeping a steady supply of food. A related problem was waste disposal for the dense population, and Cahokia is believed to have become unhealthy from polluted waterways. Because it was such an unhealthy place to live, Snow believes that the town had to rely on social and political attractions to bring in a steady supply of new immigrants; otherwise, the town's death rate would have caused it to be abandoned earlier.[19]
Decline (13th and 14th centuries)
The population of Cahokia began to decline during the 13th century, and the site was abandoned by around 1350.[28][29] Scholars have proposed environmental factors, such as environmental degradation through overhunting, deforestation[30] and pollution,[31] and climatic changes, such as increased flooding[32] and droughts,[33][34] as explanations for abandonment of the site. However, more recent research suggests that there is no evidence of human-caused erosion or flooding at Cahokia.[35][36][28]
Political and economic problems may also have contributed to the community's decline.[37] It is likely that social and environmental factors combined to produce the conditions that led people to leave Cahokia.[38][34]
Another possible cause is invasion by outside peoples, though the only evidence of warfare found is defensive wooden stockade and watchtowers that enclosed Cahokia's main ceremonial precinct. There is no other evidence for warfare, so the palisade may have been more for ritual or formal separation than for military purposes. Diseases transmitted among the large, dense urban population are another possible cause of decline. Many theories since the late 20th century propose conquest-induced political collapse as the primary reason for Cahokia's abandonment.[39]
Together with these factors, researchers found evidence in 2015 of major floods at Cahokia, so severe as to flood dwelling places. Analysis of sediment from beneath Horseshoe Lake has revealed that two major floods occurred in the period of settlement at Cahokia, in roughly 1100–1260 and 1340–1460.[40][41] While flooding may have occurred early in the rise of the city, it seems not to have deterred the city builders; to the contrary, it appears they took steps such as creating channels, dikes, and levees that protected at least the central city throughout its inhabited history.[35]
Archeologists discovered evidence in 2020 that there was a population rebound following Cahokia's population minimum in 1400, with the population reaching a population maximum in 1650 and then declining again in 1700.[42]
Notable features
The original site contained 120 earthen mounds over an area of 6 square miles (16 km2), of which 80 remain today. To achieve that, thousands of workers over decades moved more than an estimated 55 million cubic feet (1,600,000 m3) of earth in woven baskets to create this network of mounds and community plazas. Monks Mound, for example, covers 14 acres (5.7 ha), rises 100 ft (30 m), and was topped by a massive 5,000 sq ft (460 m2) building another 50 ft (15 m) high.[5]
Monks Mound
Monks Mound is the largest structure and central focus of the city: a massive platform mound with four terraces, 10 stories tall, it is the largest man-made earthen mound north of Mexico. Facing south, it is 100 ft (30 m) high, 951 ft (290 m) long, 836 ft (255 m) wide and covers 13.8 acres (5.6 ha).[43] It contains about 814,000 cu yd (622,000 m3) of earth.[19] The mound was built higher and wider over the course of several centuries, through as many as 10 separate construction episodes, as the mound was built taller and the terraces and apron were added.[43]
Monks Mounds was named for the community of
The east and northwest sides of Monks Mound were twice excavated in August 2007 during an attempt to avoid erosion due to slumping. These areas were repaired to preserve the mound.[44]
Urban landscape
Early in its history, Cahokia underwent a massive construction boom. Along with the early phase of Monks Mound, an overarching urban layout was established at the site. It was built with a symbolic quadripartite worldview and oriented toward the four cardinal directions with the main east–west and north–south axes defined with Monks Mound near its center point. Four large
To the south of Monks Mound is the Grand Plaza, a large area that covered roughly 50 acres (20 ha) and measured over 1,600 ft (490 m) in length by over 900 ft (270 m) in width. Researchers originally thought the flat, open terrain in this area reflected Cahokia's location on the Mississippi's
The major ceremonial north–south 'axis' connects the main precinct with the large ridgetop mortuary mound to its south now known as the Rattlesnake Mound (Mound 66[48]). The feature, named the Rattlesnake Causeway by archaeologists, was an elevated embankment about 18 metres (59 ft) wide, roughly 800 metres (2,600 ft) in length and varies in height from 0.5 metres (1.6 ft) to almost 1.3 metres (4.3 ft) as it traverses a low swampy area to the south of the Grand Plaza.[49] It is aligned 5° east of north, a direction thought to mimic the maximum southern moon rise of 5° west of north, albeit in reverse. This is thought to have had symbolic associations to the builders in connection with their lunar maize goddess of the underworld.[50] This is further strengthened by its close proximity to the ridgetop mortuary Mound 72, the underworld connotations of the low water-filled area the causeway traversed, and its terminus at the mortuary complex at the Rattlesnake Mound. The causeway itself may have been seen as a symbolic "Path of Souls".[49]
The high-status central district of Cahokia was surrounded by a 2-mi-long palisade that was equipped with protective bastions. A later addition to the site, when the palisade was constructed, it cut through and separated some pre-existing neighborhoods.
Beyond Monks Mound, as many as 120 more mounds stood at varying distances from the city center. To date, 109 mounds have been located, 68 of which are in the park area. The mounds are divided into three different types:
Mound 72

The falcon warrior or "birdman" is a common motif in Mississippian culture. This burial clearly had powerful iconographic significance. In addition, a cache of sophisticated, finely worked arrowheads in a variety of different styles and materials was found near the grave of this important man. Separated into four types, each from a different geographical region, the arrowheads demonstrated Cahokia's extensive trade links in North America.
Archeologists recovered more than 250 other skeletons from Mound 72. Scholars believe almost 62% of these were sacrificial victims, based on signs of ritual execution, method of burial, and other factors.[52] The skeletons include:
- Four young males, missing their hands and skulls
- A mass grave of more than 50 women around 21 years old, with the bodies arranged in two layers separated by matting
- A mass burial containing 40 men and women who appear to have been violently killed, some of these may have been buried alive: "From the vertical position of some of the fingers, which appear to have been digging in the sand, it is apparent that not all of the victims were dead when they were interred – that some had been trying to pull themselves out of the mass of bodies."[53]
The relationship of these burials to the central burial is unclear. They were unlikely to have all deposited at the same time. Wood in several parts of the mound has been radiocarbon-dated to between 950 and 1000 CE.
Excavations have indicated that Mound 72 was not constructed as a single mound, but rather as a series of smaller mounds. These mounds were reshaped and covered over to give Mound 72 its final ridge-top shape.[54]

Until the 19th century, a series of similar mounds was documented as existing in what is now the city of St. Louis, some 8 mi (13 km) to the west of Cahokia. Most of these mounds were leveled during the development of St. Louis, and much of their material was reused in construction projects.
The lone survivor of these mounds is
One of the largest Mississippian sites is Kincaid Mounds State Historic Site, located in Massac and Polk counties in southern Illinois. It is 140 mi (230 km) southeast of Cahokia, located in the floodplain of the Ohio River. With a total of 19 mounds at the complex, it is considered the fifth-largest Mississippian site in terms of the number of monuments. It is believed to have been a chiefdom, as an elite burial mound was among those found. The site is designated as a National Historic Landmark.
Cahokia Museum and Interpretive Center
The Cahokia Museum and Interpretive Center, which receives up to a million visitors a year, was designed by AAIC Inc. The building, which opened in 1989, received the Thomas H. Madigan Award, the St. Louis Construction News & Reviews Readers Choice Award, the Merit Award from the Metal Construction Association, and the Outstanding Achievement Award from the Brick Manufacturer Association.[71]
Designations
Cahokia Mounds was first protected by the state of Illinois in 1923 when its legislature authorized purchase of a state park. Later designation as a state historic site offered additional protection, but the site came under significant threat from the federal highway building program in the 1950s. The highway program reduced the site's integrity; however, it increased funding for emergency archeological investigations. These investigations became intensive, and today continue. They have resulted in the present understanding of the national and international significance of the site. The site was designated a National Historic Landmark on July 19, 1964, and listed on the National Register of Historic Places on October 15, 1966.[1]
In 1982, UNESCO (the United Nations Educational, Scientific and Cultural Organization) designated the site a World Heritage Site. This is the only such self-contained site in Illinois and among 24 World Heritage Sites in the United States in 2009.[72]
State Senator Evelyn M. Bowles wrote about the Cahokia Mounds site:
Through the years my friends and I made occasional Sunday afternoon trips to the Mounds. When I became the State Senator, it afforded me the opportunity to secure funds for the acquisition of additional acreage in which there are smaller Mounds. Many of these have contained additional artifacts.[73]
The designation has helped protect the property and attract funds to conduct research on this significant civilization.
