Art Deco Historic District Miami Ice cream cone pastels, geometric lines and curves, chrome accents and decorative fountains are just a few characteristics that distinguish the iconic buildings of Miami Beach’s Art Deco Historic District. Miami has the highest concentration of Art Deco buildings in the world, and their preservation has saved the South Beach skyline from becoming a canyon of condos. Amazingly, these buildings were nearly destroyed by developers in the early 1970s. Today, a number of the best Miami hotels, and even some South Beach clubs, have maintained their beautiful façades and historical designation.
