Constitution Hall State Historic Site

Learn about the dramatic events surrounding the drafting of the Lecompton Constitution at Constitution Hall State Historic Site and how Lecompton was affected at the Territorial Capital Museum.

Built in 1856, Constitution Hall is the oldest wood frame building in Kansas still standing in its original location. Its native cottonwood floor planks and black walnut lap siding boards were installed at the time of construction. The building witnessed the early history of Kansas Territory, and visitors can stand where that history happened. The first land office in Kansas Territory was located here, and the Kansas Supreme Court met on the second floor. The territorial legislature also met upstairs, and pro-slavery delegates wrote the Lecompton Constitution with the intent of bringing Kansas into the Union as a slave state.

Group tours are available, but the site requests two weeks prior notice for groups of 10 or more.
