Butrint 8 is largely devoted to the Middle Byzantine archaeology discovered by the Butrint Foundation’s projects at Butrint itself, in its environs, and in the nearby port of Saranda, ancient Onchesmos. The volume includes a full report on the excavations in Butrint’s western defenses, built in the 6th century as a proteichisma, and maintained in use until the 9th century when tower 1 partly perished in a fire and tower 2 was abandoned. From these 9th-century levels came a major assemblage of traded and local ceramics as well as glass cullet. The report also describes the reuse of the defenses until the 16th century when Butrint was abandoned. This volume also includes a section devoted to Butrint’s Middle Byzantine enclave occupying its hinterland, including a new study of the Dema (boundary) wall, the hilltop fortress of Çuka e Aitoit and an excavation of a settlement on the plain opposite the town. The third part of the book focuses upon Saranda, ancient Onchesmos. This includes a short report on excavations made in the port that brought to light Middle Byzantine remains as well as a major reassessment of the sanctuary church of Santa Quaranta, re-examining its Late Roman origins and its major rebuilding in the Middle Byzantine period. Butrint 8 is a benchmark for research on the Middle Byzantine period in the southern Adriatic Sea region, shedding light on an age when Butrint lay on the western limits of Byzantium, on the long-distance trade of this period, and on the character of settlement in this period.
