Why Is It Named Meridian Hill?

Pierre L’Enfant had originally planned the City of Washington around a right triangle, with the eastern portion at the Capitol, the northern portion at the White House and the 90 degree angle close to where the Washington Monument sits today. Thomas Jefferson marked this spot in 1793 with a wooden post, which was replaced in 1804 with the Jefferson Pier.

Why Is It Named Adams Morgan?

The name Adams Morgan is from the names of two formerly segregated area elementary schools—the older, all-black Thomas P. Morgan Elementary School and the all-white John Quincy Adams Elementary School, which merged in 1955 following desegregation.
