The United States Senate chamber is a room in the north wing of the United States Capitol that has served as the legislative chamber of the United States Senate, since January 4, 1859. The Senate first convened in its current meeting place after utilizing Federal Hall, Congress Hall, and the Old Senate Chamber in the Capitol building for the same purpose.
The chamber, designed by then-Architect of the Capitol Thomas Ustick Walter, is a rectangular two-story room with 100 individual desks, one per Senator, on a multi-tiered semicircular platform facing a central rostrum in the front of the room. The Senate floor itself is overlooked on all four sides by a gallery on the second floor. The Senate floor itself is 80 by 113 feet (24 by 34Â m).
