Miami Beach Architectural District, Art Deco Historic District in South Beach, United States.

The Miami Beach Architectural District is a historic district in South Beach holding 960 historic buildings, bounded by the Atlantic Ocean, Sixth Street, Alton Road, and the Collins Canal. Its hotels and commercial strips show Tropical Art Deco traits: pastel facades, horizontal "eyebrow" ledges, porthole windows, curved corners, and glass block. Ocean Drive hotels from 5th to 15th Streets face Lummus Park and the beach.

After a major hurricane in 1926 destroyed many earlier structures, architects began constructing new buildings that borrowed modern forms from the World Fairs of that era. Over the following decades, these efforts created a cohesive neighborhood that was later granted protected status.

The district's name comes from the Tropical Art Deco style, a local mix of Mediterranean Revival, Art Deco and Miami Modernism. Facades carry flamingos, palms and nautical motifs in pastel pink, yellow, turquoise and mint, and sharp corners give way to smooth edges and projecting horizontal bands known as eyebrows. Porthole windows and decorations in groups of three recur.

Walking through the area offers the best chance to notice details on facades and entrances, since many features sit at eye level. The Miami Design Preservation League organizes regular guided tours that start at the museum and last around two hours.

The district's name is tied to Barbara Baer Capitman, who founded the Miami Design Preservation League and led the campaign that secured the 1979 listing. The 1984 television series Miami Vice used many of its buildings as a backdrop, drawing new attention to the area.
