Although Constitution Square Historic Site is one of the smallest state parks, it looms large in the history of Kentucky. On June 1, 1792, Kentucky became the fifteenth state of the Union when delegates of the Kentucky statehood convention adopted the commonwealth’s constitution. This historic event took place in Danville, Kentucky at a place now known as Constitution Square. This three-acre site became part of the state parks system on October 15, 1937. Emma Weisiger donated the land for the park in memory of her brother John G. Weisiger and named it the John G. Weisiger State Park.
