Over the past decades a great progress has been made in the research of the Roman building terracotta. Numerous inscriptions provide us not only with information about the amount of material, which one worker could make over a day, but even with dates when these bricks were produced.
Typology and epigraphy started to be supplemented with petrographic analyses which base could be usedto locate the origins of the material. One of the brickyards was located near castra legionis at Vindobona and it is the only workshop discovered in the area of Pannonian Limes.
Typological parallels of stamps suggest, that Vindobona could supply all camps lying on Danube between Ala Nova and Ad Mures with building material.
