He oversaw the planning and construction of the city but died in December 1799 — before the federal government officially moved there in 1800. Washington spent most of his life at his plantation, Mount Vernon, located about 15 miles south of the city.

Beneath the U.S. Capitol complex runs a small, dedicated subway system known as the Capitol Subway System. It consists of two underground rail lines connecting the Capitol building to the House and Senate office buildings, allowing lawmakers and their staff to travel quickly between offices without going outside. The system has been in operation since 1909.

This law — not the Capitol's height — is why Washington D.C. has no skyscrapers, giving it one of the most distinctive, flat skylines of any major capital city.
