Bimini Road, Bahamas

During a diving expedition off the coast of Bimini Island in late 1968, three friends encountered what looked like a long "pavement"-like structure lining the ocean floor, around 5 meters in depth. Later dubbed the "Bimini Road", these structures stretch for over half a mile, and are formed by round stones of various sizes and thicknesses running from north-east to south-west along the ocean floor of the North Bimini coast in the Bahamas.

The precision of the formation is convincing evidence that this is not the work of nature, but a man-made formation. But what was the reason for this formation? What was it used for and why is it now on the ocean floor? At the end of the tabular road is a pronounced hook, giving it a formation similar to the letter "J". The structure is believed to be around 2,000 years old. Some explanations indicate that the structure was either a road or part of a temple structure, but the exact purpose or use of this structure, and whether it formed part of a bigger picture, remains a mystery.
