If you have the chance to tour anything behind the scenes, do it. I've now been through the Oregon Capitol and the Idaho Capitol and there is more than what you see at your first visit.
Both capital buildings were in need of seismic, fire suppression, HVAC and lighting upgrades. Idaho found a way to complete their restoration and additions while Oregon still struggles and is fixing things as they fail. These renovations are expensive, but they are so worth it, for the safety and preservation of buildings as well as for the people who work and visit the buildings. The pictures below are from Boise's building. The original began in 1904 and the renovation began in 2000. The images include a window and signed bricks from the 4th floor, the dome ceiling from the inside and out (Senate and House Wings) decorative columns inside and out and a new stairwell. Hundreds of state employees were relocated for the 9 year project. 26,000 square feet were added to the Garden level along with new ADA access.
