About Dudley-Brunswick

King

Dudley-Brunswick King, located between Roxbury Crossing and Uphams Corner, is a residential and civic Boston neighborhood with a historic street grid and a strong arts-and-institutions corridor. The neighborhood’s energy concentrates around Dudley Square (Nubian Square) at Washington Street and Dudley Street, where bus stops, murals, and small storefronts set a steady, street-level rhythm. Pillar venues include the Strand Theatre, Hibernian Hall, and the Museum of the National Center of Afro-American Artists. Triple-deckers and brick rowhouses line side streets, while larger civic buildings frame the main avenues. Pocket parks and schoolyards break up the blocks, and the MBTA Orange Line at Roxbury Crossing anchors commutes.
