Coral Castle is a stone structure created by the Latvian American eccentric Edward Leedskalnin (1887–1951) north of the city of Homestead, Florida in Miami-Dade County at the intersection of South Dixie Highway (U.S. 1) and SW 157th Avenue. The structure comprises numerous megalithic stones (mostly limestone formed from coral), each weighing several tons. It currently serves as a privately operated tourist attraction. Coral Castle is noted for legends surrounding its creation that claim it was built single-handedly by Leedskalnin using reverse magnetism and/or supernatural abilities to move and carve numerous stones weighing many tons.
The grounds of Coral Castle consist of 1,100 short tons (1,000 t) of stones in the form of walls, carvings, furniture and a castle tower. Commonly referred to as being made up of coral, it is made of oolite, also known as oolitic limestone. Oolite is a sedimentary rock composed of small spherical grains of concentrically layered carbonate that may include localized concentrations of fossil shells and coral. Oolite is found throughout southeastern Florida from Palm Beach County to the Florida Keys. Oolite is often found beneath only several inches of topsoil, such as at the Coral Castle site.
The stones are fastened together without mortar. They are set on top of each other using their weight to keep them together. The craftsmanship detail is so skillful and the stones are connected with such precision that no light passes through the joints. The 8-foot (2.4 m) tall vertical stones that make up the perimeter wall have a uniform height. Even with the passage of decades and a direct hit on August 24, 1992, by the Category 5 Hurricane Andrew, the stones have not shifted.
Many of the features and carvings of the castle are notable. Among them are a two-story castle tower that served as Leedskalnin's living quarters (walls consisting of 8-foot high pieces of stone), an accurate sundial, a Polaris telescope, an obelisk, a barbecue, a water well, a fountain, celestial stars and planets, and numerous pieces of furniture. The furniture pieces include a heart-shaped table, a table in the shape of Florida, twenty-five rocking chairs, chairs resembling crescent moons, a bathtub, beds and a throne.
