This volume describes the results of the first ten years of the joint Anglo-Georgian excavations at Nokalakevi, West Georgia. The site, known to the Byzantines as Archaeopolis, was a major fortress in the fourth to sixth centuries A.D. often described as the capital of Lazika-Egrisi. Known to medieval Georgian chroniclers as Tsikhegoji, the site is also thought to be the capital of Colchis at the time of the first unification of Georgia in Hellenistic times. Extensively excavated since 1973, and by AGEN since 2001, this is the first significant publication of results to be produced in English.
