Coral Castle

At Coral Castle near Homestead, Florida, a paranormal team left a recorder running in the tower bedroom and walked out. When they played the tape back, a voice on it asked a question: "Where is my bicycle?" The site's manager pointed out that Edward Leedskalnin's bicycle had disappeared shortly after he died — a small, specific thing almost no visitor would ever have known to ask about.

Leedskalnin is the whole story here. A Latvian immigrant who weighed barely 100 pounds, he was engaged at 26 to a younger woman most sources name Agnes Skuvst, who ended it the day before the wedding. He sailed for North America and started cutting stone. Around 1923 he began carving a monument to the "Sweet Sixteen" who never came, and he kept at it for more than 28 years.

He worked alone, mostly at night, by lantern, and would not let anyone watch. Out of over 1,100 tons of oolitic limestone he cut a heart-shaped table, a throne, a 9-ton gate balanced so finely it once swung open at the push of a finger, and a 30-ton telescope aimed at the North Star. Single stones ran to 30 tons. In the mid-1930s he moved the entire thing roughly 10 miles north, hauling it piece by piece. Asked how, he said only that he understood the laws of weight and leverage, and he took the rest with him.

In November 1951 he checked himself into a Miami hospital. He died there that December, at 64, of kidney failure. By then he'd lived inside the castle for about eleven years, and the lore is that he never really left it.

The paranormal investigator David Pierce Rodriguez believes Leedskalnin's spirit is still on the grounds, strongest in that tower bedroom. There's no record naming who saw what, no audio anyone can replay. Just a man who spent his life refusing to be watched, in a place he built and would not leave — and a recorder, decades later, asking after his bicycle.
