Topeka's first building is the historic Free State Capitol on the Kansas Territory. History was made here when free state representatives voted to ban slavery for the future state of Kansas. It also served as a local headquarters for Underground Railroad operations. Constitution Hall served as the first Kansas Statehouse, 1863-1869. The colorful outdoor mural depicts the Dispersion of the Free State Legislature in 1856. Listed by the Network to Freedom and National Register of Historic Places. While the exterior is currently under renovation, you can find a pocket park on the side of the building that details more information on local Underground Railroad history.
