Washington Navy Yard
The land was purchased under an Act of Congress on July 23, 1799. The Washington Navy Yard was established on October 2, 1799, the date the property was transferred to the Navy. It is the oldest shore base of the U.S. Navy.  The Yard was built under the direction of Benjamin Stoddert, the first Secretary of the Navy, under the supervision of the Yard's first commandant, Commodore Thomas Tingey, who served in that capacity for 29 years.
