ARCHAEOLOGICAL EXPLORATIONS NEAR THE VILLAGE OF GRANICHAK (Sergey Torbatov, Bilyana Ivanova – bil2909@abv.bg) The explorations of the Late Roman praetorium continued. Bases of pillars of a portico, built of square bricks, were documented in the anteroom of the large apsed building of the first construction period. A wall was discovered to the west of Room 2 and outside the architectural complex. It was additionally built perpendicular to the surrounding wall during the second construction period and dated after AD 364 – 367, judging from a coin. A mortar floor was discovered in Room 6 in the southeastern corner of the architectural complex. Five bases of columns of the portico in front of the western row of parallel rooms were excavated. The bases dated to the second construction period and were situated at c. 3.20 m in front of the façades of the rooms and at c. 3.50 m apart. Single Thracian sherds of the first half of the 1st millennium BC were found, when a settlement existed nearby.
