Brooklyn Heights is an affluent residential neighborhood within the New York City borough of Brooklyn. Originally referred to as Brooklyn Village, it has been a prominent area of Brooklyn since 1834. The neighborhood is noted for its low-rise architecture and its many brownstone rowhouses, most of them built prior to the Civil War. It also has an abundance of notable churches and other religious institutions. Brooklyn's first art gallery, the Brooklyn Arts Gallery, was opened in Brooklyn Heights in 1958. In 1965, a large part of Brooklyn Heights was protected from unchecked development by the creation of the Brooklyn Heights Historic District, the first such district in New York City. The district was added to the National Register of Historic Places in 1966.
