On the outside, the Capitol remained largely unchanged during this period. Inside, however, various artistic projects were undertaken to improve the Capitol's interior. In the rotunda, Constantino Brumidi began painting the 300-foot-long frieze in 1878 with scenes from American history. Sculpture was originally intended for the frieze, but Brumidi was able to achieve a similar effect with paint.
Due to a special event taking place in the U.S. Capitol on Thursday, September 18, there will be no tours of the U.S. Capitol that day until approximately noon. The Capitol Visitor Center will remain open during this time, and guided tours in the Capitol Visitor Center will be available.
