Where is the Coral Castle located?

Coral Castle is a limestone structure created by a Latvian-American named Edward Leedskalnin (1887–1951). It is located in Miami-Dade County, Florida, USA. It is a popular tourist attraction.

The structure comprises numerous megalithic stones, mostly limestone formed from coral. Leedskalnin spent more than 28 years building Coral Castle, refusing to allow anyone to view him while he worked. Books, magazines, and documentaries speculate about how one man was able to construct the structure and move stones that weigh many tons.

The grounds of Coral Castle consist of 1,100 short tons (1,000 t) of stones. Among the features and carvings are a two-story castle tower that served as Leedskalnin's living quarters, an accurate sundial, a polar telescope, an obelisk, a barbecue, a water well, a fountain, celestial stars, planets & numerous pieces of furniture.

The craftsmanship detail is so fine 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. A 9-short-ton (8.2 t) revolving 8-foot tall gate is a famous structure of the castle, and has been shown in multiple TV documentaries.

The gate is carved so it fits within a quarter of an inch of the walls. It was well-balanced, reportedly so that a child could open it with the push of a finger. In 1984 the property was listed on the 'National Register of Historic Places'.
