Since the baths probably originated mostly together with the castles, the thermal baths of the Saalburg have a long service life, which is evidenced by several conversions. [39] A sequence of construction is illustrated by the built-stamped bricks. The oldest brick temples are attributed to the Legio VIII Augusta , followed by stamps of the Legio XXII Primigenia , who stationed here Cohors II Raetorum civium Romanorum equitata ("2nd mounted court cohort of Roman civil rights") and finally as the youngest brick the Cohors IIII Vindelicorum("4 Vindeliker cohort ") from Großkrotzenburg .
