Constitution Hall is one of the oldest frame buildings west of the
Mississippi. It is said that the events that took place in this building led
to the term "bleeding Kansas" and eventually to the
Civil War. On its upper floor a pro-slavery constitution for the territory was passed, after which free-state forces rallied their supporters to eventually gain control of the territorial legislature. The building is now a museum dedicated to telling the stories of this important part of Kansas' eventual status as a free state. During the preservation
we lifted the entire structure, excavated and formed a new concrete
basement, and relayed every stone back in its original location.
We also restored the interior and designed and built the display
system. Today Constitution Hall is one
of Kansas' most visited state historic sites.
