POROS (Milen Nikolov – m_kotlenski@abv.bg, Doroteya Giurdzhiiska) The explorations continued to the east of the Roman villa and the Early Byzantine buildings. Building No. 1 was discovered, 27 m by 11.20 m in size and with three rooms. Its walls were 75 – 80 cm wide, built in rubble masonry. Piles from fragmentary tiles from the collapsed roof were discovered. A quern placed over a pad of bricks was discovered in Room No. 3. Sherds and coins of the 6th – 7th centuries AD were found, the latest coin minted by Heraclius. The building was probably a large warehouse and existed during the AD 610s – 620s. The corner of the Byzantine building that was partly explored during the previous excavations was discovered. It was 1.10 m wide, built in rubble masonry. A sector of a water-conduit was discovered, 24.95 m long. It was constructed of terracotta pipes, 55 cm long and 12 cm in diameter, bonded with mortar. The water-conduit dated to the second half of the 2nd – beginning of the 3rd centuries AD. Rectangular pits Nos. 1 – 2 were explored, containing small pieces of charcoal, sherds of the 6th – 7th centuries AD and animal bones. The finds from the excavations included two terracotta lamps of the 5th – 6th centuries AD, coins of the 2nd – 4th centuries AD and the 6th – 7th centuries AD, a lead seal, lead weights for fishing nets, small terracotta lids for amphorae, an iron tetrapod and a bronze exagium.
