SEXAGINTA PRISTA (Varbin Varbanov – ramonearhaeology@abv.bg, Deyan Dragoev) Nine ritual pits and two quadrangular constructions of the 1st century BC – 1st century AD were explored. The pits are beehive, hemispherical and with the shape of a truncated cone. They contain charcoal, fragmentary lath-and-plaster, flints, bones, spindle whorls, a mill stone, coins, a fibula, bronze objects and pottery. Remains of a building with an exedra and materials of the second half of the 2nd – 3rd centuries AD were discovered above the pits. An altar of Apollo was discovered in situ, in addition to buried fragmentary and intact votive reliefs. The building could be identified as a temple of Apollo. The wall of the temple is oriented northeast – southwest and is preserved up to 5.05 m in length and up 80 cm (including a 30 cm foundation) in height. About 50 fragments of wall plaster painted in red and white and a coin of Emperor Caracalla were found. Only three courses of the foundation of the southeastern wall are preserved at 3.60 m in length. It was cut by the northeastern wall of the later Principia. During the excavations c. 50 coins of the 1st – 3rd centuries AD were found. There are no coins of the middle of the 3rd century AD, while most antoniani of the last quarter of the 3rd century AD were burned. The southwestern wall of the Late Antique Principia was discovered, in addition to two column bases from the peristyle, part of the northwestern extension, a collapsed roofing construction and a floor level. The Principia measures 24.95 m by 16.50 m. The floor in the exedra is covered with bricks arranged on mortar padding. Twenty eight bronze coins were found on the floor level and twenty coins – under the collapsed roofing construction in the western room. All coins date to the 4th century AD. Fragmentary tiles with stamps that read RVMORID and NOVAS were found. The Principia dates to the 4th century AD.
