DEULTUM (Krasimira Kostova – kr.kostova@mail.bg) In Sector East/South 4, the explorations at the junction of the eastern cardo and the decumanus, adjoining the southeastern side of the thermae, continued. The Roman decumanus was discovered beneath the pavement of the street of the second half of the 5th – 6th centuries AD. The decumanus was paved with stone slabs and had a central drain 94 cm deep, built of stones bonded with mortar. A water-conduit of terracotta pipes bonded with mortar was explored. It was constructed when the drain was already not functional. Parallel shops arranged in a line were discovered to the south of the decumanus, built in opus mixtum. A marble base of a column placed over a pedestal was discovered on the decumanus, showing the existence of a portico that stood on the street.
