The Late Antiquity and Early Byzantine fortress Talaskara on Cape Chervenka, also known as Chrisosotira (“Golden Savior, Golden Christ”) is located on a small peninsula on the Bulgarian Black Sea coast near the resort town of Chernomorets, and 2 km northwest of the resort town of Sozopol. Not unlike the peninsula of the Old Town of Nessebar, another Black Sea resort town, Cape Chervenka has a narrow neck leading to a wider cape with an area of 68 decares (app. 17 acres), which was surrounded with a robust fortress wall with large fortress towers every 30 meters. The fortress wall of the Byzantine fortress Talaskara on Cape Chervenka (Chrisosotira) is from the 6th century, and was built as part of the large-scale fortress construction at the time of Byzantine Emperor Justinian I the Great (r. 527-565 AD).
For a long time, Cape Chervenka was a military base of the Bulgarian Navy, and Bulgarian archaeologists gained access to it only in 2014 when a team led by archaeologist Assoc. Prof. Ivan Hristov, Deputy Director of the Bulgarian National Museum of History, conducted drilling excavations with a special permit from Bulgaria’s Defense Ministry. A large fortress tower with dimensions 5 by 6 meters unearthed by Ivan Hristov’s team in 2014 is taken to indicate that the fortified Byzantine settlement located on Cape Chervenka was a rich city. The last time the fortress on Chervenka was used was during the Russian-Turkish War of 1828-1829 when the navy of the Russian Empire used it to set up a base where it accepted tens of thousands of Bulgarian refugees fleeing Ottoman Turkish atrocities who were then transported by sea to the region of Bessarabia (in today’s Moldova and Ukraine), and the Taurica (Crimean) Peninsula, and settled there.
