At this point there is a well-conserved section of pier belonging to the basin of Claudius, against which, during the Age of Trajan (98-117 AD), the buildings constituting this part of the Imperial Palace – the Castellum Aquae and the industrial Peristilium – were placed. Immediately to the east of this pier, and resting against it, other piers have been brought to light, also from the late Age of Trajan. On its front, the pier section, built in concrete with lithoid tuff aggregate bound with hydraulic mortar, shows traces of the catenae of the wooden formwork used for its construction.
