A boomtown founded in 1835, St. Joseph competed with Apalachicola as a trading port on the Gulf Coast of Florida. The original settlement lasted only nine years, but during its short life the city hosted Florida's first State Constitution Convention. The Museum commemorates the work of the 56 territorial delegates who drafted Florida's first constitution in 1838. Following four more constitution conventions, Florida was finally admitted to the Union in 1845 as the 27th state. Visitors can take a self-guided tour through displays and exhibits of 19th-century life in St. Joseph. Life-size, audio-animated mannequins in the replicated convention hall demonstrate the debate and process of drafting a state constitution.

The park offers exhibits and tours.

James Henry Lane had a significant impact on Kansas history and is one of Constitution Hall's more colorful characters. He was part of a large antislavery delegation that marched into Lecompton to protest the convening of the proslavery Lecompton Constitutional Convention in the fall of 1857. The nation's eyes were fixed on this site, waiting to see what kind of constitution would be drafted and whether Kansas would join the Union as a free or slave state. Visitors to the site can learn more about Jim Lane, the proslavery and free-state forces in the area, and other stories of territorial Kansas at Constitution Hall.

This building was the capitol for only four days in 1855, but many believe that the actions of the legislature that met here led directly to the Civil War. Governor Andrew Reeder picked this location, away from the proslavery influence of Missouri, where the legislature would choose a permanent seat of government, create a constitution, and decide if Kansas would be a free or slave state. Instead the legislature kicked out the antislavery members and passed a bill to move the government to Shawnee Mission near the Missouri border. Inside this native stone building visitors will learn the stories of the antislavery and proslavery people of territorial Kansas, set alongside the beauty of the Kaw River Nature Trail.
