PERISTERA (Boni Petrunova – boni_boon@abv.bg, Elena Vasileva, Dimitar Pavlov) Twenty-four parallel rooms were partly explored, arranged along the inner sides of the eastern and the western fortification walls and Rooms Nos. 1 – 4 were completely explored. The rooms situated along the fortification walls were built in rubble masonry and their upper parts, above 1.50 m in height, were constructed with sun-dried bricks. The roofs of the rooms were covered with tiles. The rooms were barracks, warehouses and workshops and they were destroyed by a fire. There were churches inside two fortification towers. Eighty-one dolia were discovered in the towers, the rooms and outside them. Eight exagia were found in Room No. 1: it probably was a ponderarium. The finds from the excavations included bronze coins minted from AD 285 to 592/593, weapons, tools, fibulae, sherds, a silvered copper plate from a finger-ring with a monogram that reads INNE, a church-lamp, an iron anvil, keys and locks. Two hoards with gold solidi were discovered. The first hoard comprised 12 solidi minted after AD 539 by Justinian I and one solidus of Justin II, and the second hoard comprised four solidi minted after AD 539 by Justinian I. The first hoard was buried c. AD 575/576 and the second one was buried earlier, c. AD 545 – 550, when an attack against the fortress was documented.
