What to know

Mount Vernon Square is a city square and neighborhood in the Northwest quadrant of Washington, D.C. It was originally envisioned as an open space in Pierre L’Enfant’s original plan for the city, but in the early 1800s, it was divided into four triangles by the intersection of Massachusetts Avenue and New York Avenue. The neighborhood's name is an honor consistent with the longstanding practice of commemorating George Washington. Historically, the area served as a hub of community activity. From 1846 to 1872, the square hosted the Northern Liberty Market, which was eventually demolished to make room for roadways. Development in the area was further stimulated by the Northern Liberties Fire Company firehouse, built in 1840, and the completion of 7th Street by 1822, which laid the foundation for commercial and residential growth. At the center of the square stands the Carnegie Library, a gift from industrialist Andrew Carnegie. Finished in 1903, this white marble Beaux-Arts building served as the city's central library until 1972. Notably, it opened as the city's first desegregated public building, marking a significant milestone in the District's social progress. Today, the building houses the Historical Society of Washington, D.C., and an Apple Store. In the 1990s, the neighborhood continued to transform through the construction of the MCI Arena and the opening of the Mount Vernon Square Metro station on the Green and Yellow lines. More recent urban planning efforts, such as the Mount Vernon Square District Project completed in 2010, have aimed to create a destination that attracts visitors from the National Mall and the Convention Center.
