The neo-classical building's size is impressive: it is 751ft/229m long and 350ft/107m wide. The dome including the 19ft tall statue reaches a height of 188ft or 57m. The building contains some 540 rooms spread out over five floors. Some of the most notable of these rooms are the rotunda, a large domed room in the center of the capitol and the National Statuary Hall, where statues of prominent citizens are displayed.
