The House Chamber The Chamber of the House of Representatives is the largest room in the Capitol and used today as it was originally intended in 1888. There are 150 members including the Speaker of the House who presides over the body. Due to this large number, members vote using key pads mounted on their desks. Representatives do not speak from their desks but at the podiums at the front and back of the room. There are some very important historical paintings in this room that date back nearly 100 years. In fact, the original 1836 San Jacinto Battle Flag, one of only two flags remaining from the revolution, hangs in the House Chamber during sessions. You can find the House Chamber, offices, the old Supreme Court and the House gallery in the west wing of the Capitol.
