Vindonissa (Canton of Aargau, Switzerland) was an important Roman camp during the 1st century AD. The tiles are among the most common archaeological findings in the Vindonissa legionary camp, but commonly occur in different Roman sites of Switzerland. The principal aim of this study was the petrographic and chemical characterisation of the Vindonissa tiles to determine the production site (or sites) for these ceramics and to obtain information concerning the technological aspects of the tile production and the distribution of these stamped tiles in Switzerland in Roman times.
