My wife and I arrived just after 1 p.m. and unfortunately missed the 1 o'clock tour. We took a self guided tour on our own. You must pass through security to enter. Once through, proceed to the information desk. The lady we spoke to was very helpful, giving us a map and highlighting the must see sites inside each floor of the capitol building. We were there just over an hour and a half and didn't see it all. You must pay to park, and most of the parking nearby has a 2 hour limit. Don't just run out and add more money to the meter as they mark your tire to ticket those who exceed the 2 hour limit. Touring the capitol is free and if you are into history you need to visit. Beautiful old building. Beautiful furnishings and artwork. Make sure you checkout all the bronze busts in The Hall of Famous Missourians and the room sized mural A Social History of the State of Missouri" by Thomas Hart Benton. Just incredible.
