Coral Castle is an oolite limestone structure created by the Latvian-American eccentric Edward Leedskalnin (1887–1951). It is located in unincorporated territory of Miami-Dade County, Florida, between the cities of Homestead and Leisure City. The structure comprises numerous large stones, each weighing several tons, sculpted into a variety of shapes, including slab walls, tables, chairs, a crescent moon, a water fountain and a sundial. It is currently 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 or supernatural abilities to move and carve the stones.

Edward Leedskalnin was a Latvian immigrant to the United States and self-taught engineer who single-handedly built the Coral Castle in Florida, added to the National Register of Historic Places in 1984. Leedskalnin was also known for developing theories of magnetism.
