Construction started on the United States Capitol Building in 1800, but during the War of 1812, some sections were partially destroyed. The sections were restored in a few years. By the 1850s, the building proved to be too small to house the entire US Congress, so the building was enlarged. Two wings were extended — one for each house in the bicameral legislature. In 1866, the dome that sits atop the center of the Capitol Building was completed.
