Cahokia was the jewel of the Mississippian culture, with the population of 13th-century Cahokia equal to or larger than the population of 13th-century London.

Mound City

The mounds were well-known to early explorers. French explorers and fur traders were the first Westerners to view the mounds. The mounds overlooking the river later served as landmarks for steamboat captains.

Most of the Mississippian mounds were located north of modern downtown. There were also a cluster of mounds located in Forest Park until they were plowed over for the 1904 World’s Fair. Human remains were reportedly discovered near St. Louis’ Art Museum.

Big Mound

The largest St. Louis mound was named “Big Mound”. The flat-topped, oval-shaped mound measured over 30 feet high. Despite efforts from local residents, workers dismantled the mound in 1869 and used the dirt to build the North Missouri Railroad. Meanwhile, they discovered Sea shells from the Gulf of Mexico and copper earrings in the rubble. Luckily, pictures of the mound still exist. A small memorial exists marking the site of the mound on the corner of Broadway and Mound Street.
