The Old Naval Observatory is a historic site at 23rd and E Street in Northwest, Washington, D.C.. It is where the United States Naval Observatory was located from 1844 to 1893, when it moved to its present grounds. The original observatory building, built 1839-40, still stands, and is a designated National Historic Landmark. The Washington meridian of 1850 passes through the Observatory. The property for many years housed the Navy's Bureau of Medicine and Surgery, which moved out in 2012. The property has been taken over by the State Department.
The observatory operated from 1844 to 1893 when it was closed in favor of a new U.S. Naval Observatory facility on Massachusetts Avenue. The Moons of Mars were discovered from this site in 1877.
