The Coral Castle, located near Homestead Florida, was built single-handedly by Latvian immigrant Ed Leedskalnin. Ed spent over 28 years building the Coral Castle, refusing to allow anyone to view him while he worked. From 1923 - 51 he quarried & carved over 1,000 tons of coral rock. Built under cover of night & in secret, Ed would only say that he knew “the secret of the pyramids.” He utilized mainly old car parts as leverage, pulley, & pivot tools using ancient construction methods. The stones are set on top of each other without mortar; their weight keeps them together.
Leedskalnin originally built the castle, which he named Rock Gate Park, in Florida City, Florida. It was an extremely remote location with very little development at the time. In about 1936, Leedskalnin decided to move and take the castle with him. The Coral Castle website states that he chose to move in order to protect his privacy when discussion started about developing land in the area of the castle. He spent three years moving the structures 10 miles north from Florida City to its current location near Homestead, Florida.
With few exceptions, the objects are made from single pieces of stone that weigh on average 14 tons each. The largest stone weighs 27 tons and the tallest are two 25-ft monoliths. It’s noted that Ed himself was of small stature and weighed only about 100 lbs.
Many of the features and carvings of the castle are notable. Among them are a two-story castle tower that served as Leedskalnin’s spartan living quarters (walls consisting of 8-foot high pieces of stone). There is 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. Leedskalnin continued to work on the castle up until his death in 1951. (Wikipedia article)
To this day scientists & thinkers still debate Ed’s methods. The property is privately held & is on the National Register of Historic Places.
