As Miami Beach's popularity increased, accommodations for its many visitors became in high demand. Hotels of various styles were built along the shores of the town, many in the southern section. In 1920 Carl Fisher built the Flamingo Hotel, a two-million-dollar undertaking with quite an elaborate design. Later, in the 1930s, Art Deco, a simple yet elegant form of architecture that originated in Europe, also began to show up in Miami's structures. The Cavalier Hotel was among the ocean-front Art Deco delights. Although many of the original hotels have been torn down, those that still stand have been restored and remain a part of the beach's historic district.
