EXPLORATIONS IN POROS (Tsonya Drazheva, Milen Nikolov – m_kotlenski@abv.bg) The explorations of the structures in the harbor of Poros, situated on Phoros Peninsula, continued. Tower No. 1, 9.20 m by 9.60 m in size, was explored. It was preserved up to 4.60 m in height. The tower protected the harbor and probably also the wooden bridge known from the historical sources. The tower was put on maritime maps from the 13th to 17th centuries. Its construction was related to securing the protection of the territory of Deultum in the 2nd century AD. The tower was built of ashlars bonded with mortar with an emplectum of roughly cut stones and mortar. A Roman bronze coin of Antoninus Pius and a bronze coin of the 4th century AD were found at its eastern wall. A well, 1.30 m in diameter, was explored in front of the eastern foundation of the tower. A bronze Ottoman coin of the second half of the 14th century was found inside the well. The bedrock to the east of the tower was cut out in order to accommodate a quay, 12 m long and 18 m wide. Foundations constructed in rubble masonry, belonging to a building 4.60 m by 5.80 m in size, were discovered. The finds included a hoard of bronze coins with small nominal value dated to the 5th century AD, iron nail and clamps, and pottery from the 5th to 17th centuries. The finds indicated that the quay was used in the period when the tower was functional. Tower No. 2, 5.20 m by 7.50 m in size, was explored at 23 m to the north of Tower No. 1. Its walls were 1 m wide and preserved up to 80 cm in height. The southern wall of the tower was constructed over a funerary chamber, 2.10 m by 0.75 m in size, oriented east – west, and built of stone slabs. The skeleton of the deceased was badly preserved. Sherds from the 3rd – 2nd century BC, an iron ring and an iron handle were found inside the funerary chamber.
