WASHINGTON | DC
Mount Vernon Square is a city square and neighborhood in the Northwest quadrant of Washington, D.C. The square is located where the following streets would otherwise intersect: Massachusetts Avenue NW, New York Avenue NW, K Street NW, and 8th Street NW. On the north side of the square is the Walter E. Washington Convention Center, the second largest building in the city after the U.S. Capitol. On the south side is the Techworld office development, on the east the former offices of National Public Radio, and on the west is the Neoclassical marble Mount Vernon Place United Methodist Church, located at 900 Massachusetts Avenue NW, is a nearby landmark due west of the square.
In the center of the square is the District of Columbia Public Library, now home to the Historical Society of Washington, D.C. The white marble library building, finished in 1903, was a gift of industrialist Andrew Carnegie. It was built where a public park once stood. Prior to the park, the site was occupied by the old Northern Liberty Market demolished by Governor Alexander Shepherd in a night raid with two to three hundred men. Washington's Chinatown is two blocks to the south, and the White House seven blocks to the southwest. The closest Metro station is Mt Vernon Square. Mount Vernon Square is also a Washington neighborhood and historic district, named for the adjacent city square, bounded by 9th Street NW on the west, 1st Street and New Jersey Avenue NW on the east, N Street NW on the north, and Massachusetts Avenue NW to the south. Originally, Victorian-style townhomes occupied this area. It was originally a vibrant business district with sizeable Victorian homes, but the area went into a steep decline in the 1930s.
In 2005, Boston Properties constructed 901 New York Avenue NW in Washington, D.C., helping to revitalize the Mount Vernon Square neighborhood. On November 10, 2011, ground was broken on the 14-story Washington Marriott Marquis, a $520 million, four-star, 1,175-room "convention center headquarters hotel" with more than 100,000 square feet of meeting room space. The new hotel is adjacent to and northwest of the square. The Association of American Medical Colleges (AAMC) purchased the Mount Vernon Triangle site of land at Seventh and K streets N.W. to build their new 300,000-square-foot headquarters. The association will be moving from their current location in the West End to occupy the property by the fourth quarter of 2013 in a sleek modern building.
