Burgas scientists announced today that they have uncovered a monumental building measuring 7.60 metres in width beside the inner southern wall of the medieval town of Rusokastro. The structure’s walls are 1.1 metres thick and constructed of stone with abundant mortar. The interior surfaces bear a thick layer of pink, hydrophobic plaster, indicating it was likely used as a water reservoir or a food‑storage facility, BTA reported.
Burgas Media added that the building’s archaeological layer revealed a ground floor and a second residential floor above, hinting at a multifunctional use in the central quarter of the city. It also uncovered a large number of artifacts, including silver coins issued during the reign of Bulgarian Tsar Ivan Alexander and Venetian silver grosso coins, it said.
Burgas Media noted the find was part of the state‑funded excavation program managed by the Regional History Museum of Burgas and financed by the Council of Ministers and Kameno Municipality. The Museum’s restoration laboratory is currently cleaning and conserving the recovered coins and other items.
Both BTA and Burgas Media highlighted Rusokastro’s historical role in the 14th‑century Bulgarian‑Byzantine conflicts. The site was the site of a decisive battle on 18 July 1332 in which Tsar Ivan Alexander defeated a Byzantine army under Emperor Andronicus, BTA recounted. The fortress was later destroyed during Ottoman campaigns in 1443.
