ARCHAEOLOGICAL EXPLORATIONS IN DEULTUM (Hristo Preshlenov – hristo.preshlenov@abv.bg) The explorations of the ‘Public Building’ Site were carried out in 1986 – 1992 and in 2004 over an area of c. 1250 sq. m. The following structures were discovered: monumental buildings related to the cult of Asclepius from the time of the Severan dynasty, houses and farm buildings constructed of stones or mud bricks, and a fortification wall with a bastion which barred the decumanus from the east. The explorations continued over an area of 100 sq. m. A segment of the decumanus was discovered. The pavement consisted of huge stone slabs placed over trampled clay. The curbstone consisted of two rows of ashlars. The finds include two coins of Emperor Constantine I, one minted in Antiochia in AD 325/326 and one in Cyzicus in AD 332/335. A drum of a column and a fragment of a capital were discovered. A room with roofing covered with tiles, which had been burned, was documented. Changes in the urban model in this part of Deultum occurred after the middle of the 4th century AD. A building with an entrance from the east, which covered part of the decumanus, was constructed. Probably during the 5th century AD, the building was partitioned. Its walls were 75 cm wide and were constructed of uneven stones and reused ashlars bonded with mortar. The building had a floor paved with bricks and a roof covered with tiles. At the moment, the ramshackle building, discovered in 2004 and dated by a coin of Emperor Maurice minted in AD 594/595 and a coin of Emperor Phokas minted in Nicomedia in AD 604/605, indicate the latest occupation period of this part of Deultum.
