Constitution Square State Historic Site

Constitution Square State 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. On March 6, 2012, the Department of Parks ceded control of the site to the county government of Boyle County, Kentucky.

The park celebrates the early political history of the U.S. state of Kentucky. It features replicas of three buildings that stood on the original city square, including the courthouse that housed ten constitutional conventions between 1785 and 1792; these conventions ultimately led to Kentucky's separation from Virginia. It also includes the original building that housed the first U.S. post office west of the Allegheny Mountains and several other early 19th century buildings of historical import. The site comprises the majority of the Constitution Square Historic District which was added to the National Register of Historic Places on April 2, 1976. Among the annual events held at the site are the Great American Brass Band Festival and the Kentucky State Barbecue Festival.
