ARCHAEOLOGICAL EXPLORATIONS NEAR THE VILLAGE OF GRANICHAK (Dobrin Antonov, Nartsis Torbov – natorbov@mail.bg) The explorations of the mansio that existed in the 4th century AD continued. The western surrounding wall of the mansio makes a right angle and continues to the east. It is preserved at 70 m in length and marks the northern end of the mansio. The area between the eastern wall of the baths and the western surrounding wall of the mansio was explored. A layer with ancient debris thick up to 30 cm was discovered. Part of Room No. 3 of the baths was explored at 4 m in length and 3.60 m in width. The floor was constructed of mortar and broken bricks. The room adjoins the surrounding wall of the mansio and most likely it was built later than the baths. The banquette and the northwestern corner of its wall were discovered. The explorations of Rooms Nos. 1 and 2 of the baths were concluded. Room No. 1 measures 3.35 m by 3.12 m and Room No. 2 measures 3.35 m by 2 m. The area outside the western wall of the baths was explored. The hypocaust of the central building of the mansio was explored.
