The main square of the harbour district was the so-called Hall of Verulanus. This spacious square, measuring 200 by 240 meters, used to be the largest of the sports facilities situated along Harbour Street. Its name comes from the founder, Verulanus, who was the chief priest of Asia during the reign of Emperor Hadrian. He ordered paving and tiling of the greater of the palestrae of the Harbour Baths with marble slabs in 13 different shades. These panels have not been preserved to our times, but their existence is evidenced by the holes in the walls, where the panels were attached. This arcaded courtyard served as training grounds of the athletes. Called xystos in antiquity, the court was surrounded by a three-aisled colonnade with its broad middle aisle serving as a running track. The best opportunity to glimpse the ruined Hall of Verulanus is to look at its eastern corner, recently uncovered by the archaeologists next to the Church of Mary.
