The Early Byzantine fortress on Akra Cape dates back to 6th century, when on the narrowest part of the cape, a solid fortress wall safeguarding an area of 16 daa was built. Parts of fortified walls and towers have been preserved until the present day and reach height of up to 4 meters.

During an archaeological study conducted in the region of the fortress in 2012, remains of a town were discovered, 2/3 of which were located on the land, and the rest were under water. Numerous coins, adornments, ceramics, and fragments of glass objects were discovered too.

The project envisages continuation of the archaeological studies, emergency conservation and restoration of the discovered structures, installation of impressive lighting, construction of pertaining infrastructure, and ensuring accessible environment for people with specific needs.
