About: Mount Vernon Triangle

Mount Vernon Triangle is a neighborhood and community improvement district in the northwest quadrant of Washington, D.C. Originally a working-class neighborhood established in the 19th century, present-day Mount Vernon Triangle experienced a decline in the mid-20th century as it transitioned from residential to commercial and industrial use. The neighborhood has undergone significant and rapid redevelopment in the 21st century. It now consists mostly of high-rise condominium, apartment and office buildings. Several historic buildings in the neighborhood have been preserved and are listed on the National Register of Historic Places. Mount Vernon Triangle is now considered a good example of urban planning and a walkable neighborhood.
