Excavations reopened at Rione Terra. During the laying of a sewer pipe at the foot of the acropolis, in the area of the present port, three large quadrangular pillars in opus caementicium, faced with opus latericius came to light. Standing circa 2 m apart they were preserved to a height of circa 5 m and rested upon a base of piperno opus quadratum, comprising at least two courses of blocks which showed heavy signs of marine erosion. On top of the easternmost pillar was the impost of an arch, also in opus latericius, on an east-west alignment. An attractive and rather probable hypothesis suggests these pillars were part of the arch which must have stood at the entrance to the famous so-called “Caligulan” wharf. This was still visible at the beginning of the 20th century before being incorporated into the modern wharf.
