Just 38 feet in circumference and made up of 24 holes or basins cut into the limestone bedrock in downtown Miami Florida is possible evidence of a henge dated 1500 to 2000 years old. Thought to be artifacts of the Tequesta Indians, or Keys Indians, the henge was uncovered in 1998. On the south side of the Miami River, on the eastern shore of the mainland between South Beach and the bridge to Key Biscayne, the site occupies prime real estate.
Archaeologists from Miami-Dade County’s Historic Preservation Division decided that the holes were used for support posts of a large round structure. They surmised the Tequesta Indians (who disappeared before the Seminoles migrated to Florida) were responsible. Developers posited that the circle was an old septic tank and that the holes were overflow drain holes. Ancient Alien theorists said the circles were a launching pad for a worldwide ancient race of stellar visitors.
Finally, the Miami Circle was designated the Brickell Point archaeological site. It sits on land once owned by William Brickell, a pioneer who ran an early trading post. The site has been studied finding two hundred other postholes cut in the limestone in addition to the ones forming the Miami Circle.
