The St. Charles County Heritage Museum, located at 1630 Heritage Landing, St. Peters, offers free interpretive displays focusing on local and state history. A small meeting room is also available to reserve. The park's Centennial Trail provides an easy connection to the Katy Trail.
Visit the Heritage Museum to view the new exhibit, "The American Revolutionary War in the West". The exhibit features rare artifacts, original documents, uniforms, flags and interactive components that explore life in the Mississippi River Valley region during the American Revolutionary War and western contributions to the war. This exhibit gets its name from a new book by St. Louisan Stephen L. Kling Jr. His book and the exhibit focus on the war in the west, which has been largely ignored until recently. Other exhibits throughout the museum delve into the history of St. Charles County during the Colonial era and the War of 1812.
