Constitution Square Historic Site is a 3-acre (0.012 km2) park and open-air museum in Danville, Kentucky. From 1937 to 2012, it was a part of the Kentucky state park system and operated by the Kentucky Department of Parks. When dedicated in 1942, it was known as John G. Weisiger Memorial State Park, honoring the brother of Emma Weisiger, who donated the land for the park. Later, it was known as Constitution Square State Shrine and then Constitution Square State Historic Site. On March 6, 2012, the Department of Parks ceded control of the site to the county government of Boyle County, Kentucky, and its name was then changed to Constitution Square Historic Site.
