The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near the island of North Bimini in the Bimini chain of islands. The Road consists of a 0.8 km (0.50 mi)-long northeast-southwest linear feature composed of roughly rectangular limestone blocks. Various claims have been made for this feature being either a wall, road, pier, breakwater, or other man-made structure. However, credible evidence or arguments are lacking for such an origin.[1]
