PHILIPPOPOLIS (Maya Martinova – maya_martinova@abv.bg) The site was situated at c. 100 m to the north of the Eastern Gate of Philippopolis. During the 11th – 12th centuries, a Christian cemetery existed there. Two intact burials were explored and several burials destroyed by later building activities were documented. During the 4th century AD a building extra muros was constructed there. The central room with octagonal layout was explored; there was a semicircular niche on its southwestern side. Two floor levels and some of the plaster on the inner sides of the walls were documented. The upper floor was covered with polychrome mosaics arranged over a mortar bed. Another room was explored to the northwest of the central one. It had a hypocaust with pilae constructed of bricks; cylindrical tubulae from the wall heating were found as well. The building existed during the 4th – 6th centuries AD and two construction periods were documented. A wall of a building with a floor of trampled clay was explored, built of ashlars whose joints were plastered with mortar. The building dated to the late 1st – 2nd centuries AD.
