When it opened, the Capitol structure was large enough to host all the state agencies and departments. Due to the growth of state government, however, only the offices of Senate and House leadership and ceremonial offices for the governor and lieutenant governor remain in the capitol. The ground floor corridors led to "store rooms" designed by the architect in the original building plans. This includes an armory in the southwest corner of the south corridor. The original wood floor has been replaced by gray tiles. The rooms were originally lit with gas fixtures, though by 1900, the building had been refitted with electric lights. Today, the ground floor is home to several offices, including the Secretary of the Senate, the Clerk of the House, and the Capitol Tours and Information Service.
