Stiltsville is a group of wood stilt houses located one mile south of Cape Florida, on sand banks of the Safety Valve on the edge of Biscayne Bay in Miami-Dade County, Florida. The structures stand on wood or reinforced concrete pilings, generally ten feet above the shallow water, which varies from one to three feet deep at low tide.

Stilt houses are houses raised on stilts over the surface of the soil or a body of water. Stilt houses are built primarily as a protection against flooding; they also keep out vermin. The shady space under the house can be used for work or storage. Stilt houses are commonly found in Southeast Asia, Oceania, Central America, Caribbean, northern parts of South America, Madagascar, Mauritius, Seychelles and the Maldives.
