The National Statuary Hall is one of the most popular locations in the U.S Capitol Building, with tourists flocking year-’round to see the collection of statues from across the 50 states. The hall is one of the earliest examples of Greek revival architecture in America. The hall has the shape of an ancient amphitheater, with pilasters made of sandstone and columns made of Breccia marble quarried along the Potomac River. The Corinthian columns were carved from white marble in Carrara, Italy.
