SERDICA (Yunian Meshekov – meshekov@abv.bg) A partly preserved Early Christian barrel-vaulted tomb was explored to the north of St. Sophia Basilica. It was previously discovered during building works in 1989. The tomb was built of bricks bonded with mortar; it was oriented northeast – southwest and its burial chamber measured 3.30 m by 2.20 m. The entrance was 1 m high and 55/60 cm wide, oriented to the southwest and closed with a stone slab. Single human bones were discovered scattered in the burial chamber. There were frescoes on the wall of the chamber: two Latin crosses painted in red and floral decoration painted in green and red, representing garlands with rosettes on stems. The tomb dated to the end of the 5th – beginning of the 6th centuries AD.
