ARCHAEOLOGICAL EXPLORATIONS IN PLOVDIV (Ivo Topalilov – itopalilov@yahoo.com) The site is located at MacGahan Street, inside the fortification of Philippopolis. A sondage, measuring 7 m by 3 m, was carried out. Cultural strata down to 3 m in depth were explored. The earliest cultural stratum contained debris from a building constructed of sun-dried bricks, with a floor of trampled clay. Postholes were discovered. The finds include animal bones, sherds, including from black-gloss pottery, and coins of the end of the 4th century BC. A later building, dated to the beginning of the 3rd century BC, lies over the debris of the earlier one. Its construction was identical. Fallen wooden beams from the roofing and fragmentary roofing tiles were found. The building was burned. A later building lies over it: its foundations constructed of stones and its walls built of sun-dried bricks. Several floor levels of trampled clay were documented. Judging from the coins that were found, the building existed during the first half of the 2nd century BC. It was burned. Two pits, 96 cm and 1.20 m in diameter, were discovered. They contain sherds, a bead and a coin of Alexander the Great. Two rooms from the Roman period were explored. Initially their walls were built of uneven stones bonded with mud. Later, walls of uneven stones bonded with mortar were constructed on the earlier ones. A drain built of bricks bonded with mortar was discovered in room No. 1. Three floor levels were discovered in room No. 2. The finds include sherds, a dolium, terracotta lamps, a terracotta head of Athena, a coin of Antoninus Pius minted in Philippopolis, an iron ring key, iron knives, a small bone spoon, weights of fishing nets, roofing tiles and slag. After a fire, a new building was constructed with a different layout. It was built of uneven stones bonded with mortar. The buildings date to the 2nd – 3rd centuries AD.
