The
Washington Monument and the
Jefferson Pier are near the center of the mall, south of the
White House. Directly northwest of the Washington Monument is
Constitution Gardens, which includes a garden, park, pond, and a
memorial to the signers of the
United States Declaration of Independence. Just north of Constitution Gardens is the
Lockkeeper's House, which is the second-oldest building on the mall after the White House. The house is operated by the
National Park Service (NPS) and is open to the public. Also on the mall is the
National World War II Memorial at the east end of the
Lincoln Memorial Reflecting Pool; the
Korean War Veterans Memorial; and the
Vietnam Veterans Memorial.
