History

Prior to the arrival of Europeans, the area that would become St. Peters was inhabited by Mississippian mound builders. The remains of a village were uncovered during the construction of I-70 in 1954 and a street near the site was later named Mound Drive after the mounds built by the villagers.

One of the first documented sources about European settlers in the area is a Spanish census from 1791, which documented a land grant. St. Peters was named for a Jesuit mission established there. In 1895, music was a binding factor for the area, with a well-known cornet band.

Throughout most of the twentieth century, St. Peters was a small farming town. As recently as 1970, St. Peters had a population of only 486. The population rapidly increased to 15,700 by 1980 and within the span of a decade the community changed from a small rural town to a more suburban community. The city continued its rapid growth through the 1980s and by 1990 had a population of 40,660. St. Peters population increased to an estimated 52,575 as of 2010. St.Peters celebrated its 50th year as a city in 2009, and marked its 100th year as a town in 2010, having become a town in 1910 and a city in 1959.
