The study of marble trade in antiquity has received a lot of scholarly attention in the last few decades; however, numerous deposits of high-quality white marble in the Thracian interior have only recently become pivotal in Bulgaria. Following the establishment of Thrace as a Roman province, investments into transport infrastructure, urban and rural construction works and monumentalizing architecture in marble have led to an increased demand for stone. Local marble quarries close to urban centres and larger imperial quarries were used for civic buildings, villas and sanctuaries. Provenance analysis of marble quarries and artefacts has established a close link between the place of origin and subsequent place of use. This multi-disciplinary study explores marble sources in the Thracian interior via various approaches such as epigraphy, archaeology, and archaeometry regarding urbanization, trade, and transportation. In this paper, we consider and investigate the Berkovitsa marble, a quarry close to Montana in northwestern Bulgaria, and present a broader framework for the marble trade of the region.
