The ancient and medieval fortress and port of Burgos (Poros) is located on the Cape of Foros in the Bulgarian Black Sea city of Burgas. It was first first excavated in 2008 by archaeologists Milen Nikolov (currently Director of the Burgas Regional Museum of History), Dr. Tsonya Drazheva, and Konstantin Gospodinov, after access to its site was denied for decades because of the existence of a nearby military base which has been closed down in recent years.
Part of its fortress wall was first discovered in 1989 during the construction of a cow farm. Even though there have been traces of ancient life, the fortress and port city of Burgos (Poros) on the Cape of Foros in Bulgaria’s Burgas is dated back to the Late Antiquity / Late Roman period, with the Bulgarian archaeologists uncovering a large number of buildings, artifacts, and pottery vessels dating back to the 4th-6th century AD.
Their excavations have revealed a complex set of fortifications, including walls, ramparts, and towers, which were rebuilt and reorganized multiple times from the 4th until the middle of the 15th century, and were in use throughout this entire period by different states: the Roman Empire, the Byzantine Empire, the Bulgarian Empire, the Ottoman Empire. Some of the more interesting finds including a stone block with an Ancient Roman inscription in Greek mentioning the name of Roman Emperor Gordian III (r. 238-244 AD); a 2nd century AD inscription carved into stone stating that “burgi” (fortifications) were built on the border of the Roman colony of Deultum (located some 10 km inland from the Black Sea coast near today’s town of Debelt) – hence, possibly, the name Burgos; a basilica; the remains of a small monastery called “St. George” which is described in a 13th century Byzantine source; the 6th century lead tube reliquary containing ashes from the grave of John the Apostle in Ephesus, Anatolia.
The Foros pennisula was marked on Italian and Catalan maps from the 13th-17th century as an old fortress and port under the name Poro (strait) or Poros, which means that the fortress defended the waterway entry point of the nearby Lake Mandra which flows out into the Black Sea. A stone inscription dating back to the 2nd century AD (presently exhibited in the Burgas Regional Museum of History) discovered on the site states that “burgi” (fortifications) were built on the border of Roman colony Deultum (located some 10 km inland from the Black Sea coast near today’s town of Debelt). Historians believe that there used to be a large fortified port along the waterway between Lake Mandra and the Black Sea which served and protected the Roman city of Deultum. The Roman road station called Pudizo marked in the 4th century Tabula Peutingeriana (the Peutinger Map showing cursus publicus, the road network in the Roman Empire, covering Europe, North Africa and parts of Asia) has been discovered in this same area.
The area of the Burgos (Poros) fortress and the Cape of Foros is also famous for being the site of a major battle during the Second Bulgarian Empire (1185-1396 AD). The so called Battle of Skafida (named after the Skafida River and the Skafida Fortress, another medieval fortress located nearby) took place in 1304 AD when the forces of Bulgarian Tsar Theodore Svetoslav (r. 1300-1322 AD) defeated the army of Byzantine Emperor Michael IX Palaiologos (Palaeologus) (r. 1294-1320), after having reconquered earlier the nearby Black Sea cities of Rusocastro, Mesembria, Anchialos, Sozopolis and Agathopolis. The victory in the Battle of Skafida helped the Second Bulgarian Empire regain most of the region of Thrace from Byzantium bringing it a period of relative stability at the beginning of the 14th century, after feudal strife had put it in a state of permanent dynastic crisis at the end of the 13th century.
