This S. Kansas Avenue pocket park commemorates the intersection of four unique, nationally significant historic events here on S. Kansas Avenue: In Constitution Hall was the Topeka Constitutional Convention in 1855, the Dispersal of the Free State Legislature on July 4, 1856, activities of the Underground Railroad on the Jim Lane Trail in 1857, and nearly 100 years later in the Old Federal Building across the avenue from Constitution Hall, the 1951, federal case trial  leading to the landmark 1954, Brown v. Board of Education Supreme Court decision.
