Senators meet in the Senate Chamber to debate and vote on legislation impacting the lives of all Ohio residents. A major renovation in 1996 restored the chamber to its original nineteenth century design and updated the room with modern technology including state-of-the-art video cameras, an electronic voting system and laptops for the senators to view the bills on which they are voting.

At one time, each senator’s desk would have served as his or her office in Columbus. Today, all senators have individual office space. Although the Senate President has a desk on the floor, he presides from his podium at the front of the chamber. The President’s mahogany and walnut chair and the marble dais are original to the building. The dais was carved on site from a large piece of marble that had to be moved into the building before the construction of the walls.

The Senate Chamber is the same size as the House Chamber, but with one-third the number of desks, designed to replicate the originals. Like the House, the Senate Chamber once contained a visitors' balcony. The columns in the back of the room show marble patchwork where the former balcony was attached. Though primarily reserved for legislative business, the Senate Chamber also served as temporary quarters for Civil War soldiers and at times as a venue for dancing and celebrations.
