Located on the second floor, the House Chamber was originally used as an official meeting room for debating and passing state laws.
The writing and approving of the Act for Statehood in 1846, the Constitution of 1846 and 1857, and the Code of Iowa 1851 took place in this room. When the Old Capitol started to be used as a University building, this room was a chapel where daily services were held. From 1880, this room was used for the law department, divided into three rooms; a classroom, a library, and an office.
