EXPLORATIONS IN ABRITUS (Galena Radoslavova – galena_rz@abv.bg, Georgi Dzanev) A sondage was carried out in the ‘Early Christian Complex’ Sector. It was situated to the north of tower No. 13, in front of the eastern fortification wall. Debris and remains from all occupation periods of the castellum were found down to 60cm in depth. A layer of debris from the eastern fortification wall was explored from 0.60 to 1 m in depth. A layer, containing burned mud bricks, pottery of the 4th – 5th centuries AD and 28 bronze coins minted from the middle of the 4th to the second half of the 5th century AD, was explored from 1 to 1.60 m in depth. The eastern fortification wall was built after the end of the 5th century AD. Part of a Late Antique house, situated under the floor of the eastern room of the basilica, was explored inside the castellum. Two parallel walls of the house were documented. The walls, 50 – 53 cm wide, were built of uneven stones bonded with mortar, and were situated at 2.80 m from each other. A drain built of bricks was explored between both walls. The floor of the house was paved with bricks. Sherds of the 4th – 5th centuries AD and 80 bronze coins of the 4th – end of the 5th centuries AD were found in the debris of the house. The coins date the destruction of the house to the end of the 5th century AD. An ashlar with incised cross was incorporated in the foundations of the apse of the basilica. The bases of the columns, arranged in a line oriented east – west, as a continuation of the southern wall of the basilica, were discovered. The bases were reused Roman altars with Latin inscriptions. According to one inscription, three persons, veterans and Roman citizens who settled in ‘Abritto lustro’, made a dedication to a deity.
