On June 30th, Ken Salazar, Secretary of the Interior, approved the addition of Congressional Cemetery to the Register of National Historic Landmarks.
National Historic Landmarks are buildings, sites, districts, structures, and objects that have been determined by the Secretary of the Interior to be nationally significant in American history and culture. Many of the most renowned historic properties in the nation are Landmarks. Congressional Cemetery shares this designation with the Capitol, White House, Supreme Court, and Washington Monument.
