This work presents an archaeometric study on the Vindonissa stamped tiles. Vindonissa (Canton of Aargau, Switzerland) was an important Roman camp during the 1st century AD. With Vindonissa stamped tiles, archaeologists refer to all tiles stamped with thename of the military units that were stationed at Vindonissa from 47 to 101 AD. These tiles are among the most common archaeological findings in the Vindonissa legionary camp, but commonly occur in different Roman sites of Switzerland. The princAal 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.
