The apparent hiatus before completion of the amphitheatre (1b) has been linked to a change in the resident garrison. When this building was in turn replaced it was encased by the successor amphitheatre (2), which was constructed on a scale that makes it the largest example currently known from Roman Britain. Sadly, as the excavators note, “the level of survival [...] is in inverse proportion to its original size and form” (p. 162). Nevertheless, ingenious study of the surviving structural elements allows a somewhat austere superstructure to be reconstructed with a high degree of certainty.
