Cape Akra Fortress, located on the Akra Peninsula near Chernomorets on Bulgaria's Black Sea coast, is an Early Byzantine fortification built in the second half of the 5th century under Emperor Anastasius. The fortress protected a settlement on the narrowest section of the cape, with preserved fortification walls and towers reaching heights of 4 meters. The site remained in use until the late 6th century when it fell to Avar invasions. Positioned at the sea's edge, the fortress offers visitors direct access to Black Sea coastal landscapes and remains an important archaeological site documenting early Byzantine maritime defense strategies along the Bulgarian coast.
