Mediterranean, Streamline Modern and Art Deco are all represented in the District. The Historic District is bounded by the Atlantic Ocean on the East, Lenox Court on the West, 6th Street on the South and Dade Boulevard along the Collins Canal to the North. The movement to preserve the Art Deco District's architectural heritage was led by former interior designer Barbara Capitman, who now has a street in the District named in her honor.
