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. The structure comprises numerous megalithic stones (mostly limestone formed from coral), each weighing several tons
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.
Edward spent over 28 years building the Coral Castle, refusing to allow anyone to view him while he worked and continued to work on the castle up until his death in 1951
With few exceptions, the objects are made from single pieces of stone that weigh on average 15 short tons (14 t) each. The largest stone weighs 30 short tons (27 t) and the tallest are two monoliths standing 25 ft (7.6 m) each.
Many have speculated that mystical forces were used to move the Coral blocks that weighed many tons. Edward Leedskalnin understood the laws of weight and leverage.
