The Old Senate Chamber is a room in the United States Capitol that was the legislative chamber of the United States Senate from 1810 to 1859 and served as the Supreme Court chamber from 1860 until 1935. It was designed in Neoclassical style and is elaborately decorated. In 1976 as part of the United States Bicentennial celebrations, it was restored to the appearance of when it served the Senate in the 1850s; it is preserved as a museum and for the Senate's use.

The United States Capitol building features a central rotunda below the Capitol dome. Built between 1818 and 1824, the rotunda has been described as the Capitol's "symbolic and physical heart".
