Archaeologists have found a 6900-year-old stone road at the bottom of the Adriatic Sea

Archaeologists from the University of Zadar discovered the ruins of a Neolithic settlement and the remains of a road built almost 7,000 years ago. In ancient times, this route connected the mainland with the island of Korcula in Croatia.

The ancient underwater route is located at a depth of about five meters. In footage taken by divers in Gradina Bay, a paved stone path is visible under a layer of silt and seaweed. Scuba archaeologists use special tools to remove sand and excavate an architectural monument.

For experts, it remains a mystery how our ancestors adapted and built roads to connect different parts of the land. According to archaeologists, the trail was at the top of an artificially created structure such as a dam.
