Old Jamestown originally was known under a variety of different names during the early years have been Coldwater, Patterson Settlement, The Sinks, and Jamestown. In 2010, Old Jamestown became officially recognized as an unincorporated portion of the St. Louis community.
Throughout its history, the Old Jamestown region was mainly made up of a low density, strongly wooded rural environment, intermingled with active farms. Situated along the bank of the Missouri River, the community was a few miles upriver from the convergence of the Missouri and the Mississippi and has a rich history dating back to ancient times. Old Jamestown’s history includes an American Indian settlement associated with Cahokia Mounds, land grant holders of English and Scottish heritage who arrived in the late 1700s, German immigrant farmers who came during the 1800s, and prominent wealthy families who arrived in 1920 throughout 1940.
