Behind the Severan Warehouses, against the back wall and facing the basin of Claudius, various structures were installed on a small, internal beach in Late Antiquity, including a building made with the masonry technique defined as opus vittatum mixtum, characterized by rows of rectangular tuff blocks alternating with rows of bricks. Of this building, seven tabernae arrayed in a row and identified by their typical thresholds are conserved, as well as the remains of a portico in front, of which only the first pillar remains. Below this system an older sewer, covered with travertine blocks, ran in an east-west direction from Trajan's basin parallel to the long arm of the Severan Warehouses.
