ARCHAEOLOGICAL EXPLORATIONS IN SCRETISCA (Ventsislav Dinchev – vdintchev@abv.bg) A sondage in the central part of the yard of the Late Roman residence Scretisca, which coincided with the central sector of Early Byzantine Kratiskara, was carried out. The northern wall of a building of the 6th century AD, built of stones and fragmentary bricks bonded with mud, was discovered. An earlier wall of the Late Roman period was documented. It was 50 – 52 cm wide and was built of stones bonded with mortar. A layer of mortar was reached at c. 1.70 m depth. A drain, 60 cm deep and 60 – 70 cm wide, was discovered within the mortar. Sherds, mostly from pots and lids, were found during the excavations. Fragments of red-gloss pottery were found inside the drain.
