This season, a 10 × 20 m trench was opened in the previously unexcavated area of Ghiacciaia where an intensive survey was undertaken by Venice Ca’Foscari University between 2012 and 2015. The area is situated in the northern part of the Roman city of Altinum, just east of the monumental centre, where the forum, basilica, theatre, and odeon stand. The excavations uncovered structures and rooms relating to the urban residential quarter, unfortunately heavily cut by the ploughing that took place here until the 1970s when the State acquired the Ghiacciaia in order to protect and enhance the buried archaeological structures. At least three rooms belonging to a domus were uncovered, divided by walls of which only the foundations remained, as they had been robbed out in the late antique period. The patchy remains of a cement-mortar floor make up were found in only one of the rooms. One of the foundations, characterised by the presence of squared stone blocks, seemed to represent the east wall of the domus. It was adjacent to the large robbing trench of a cloaca, of which a single brick-built structural section was found, formed by the floor and side parapets, while it must have been covered by the large trachyte stone blocks, found in secondary deposition in the trench fill. East of the cloaca, into which a smaller perpendicular sewer must have run, there was another room, of which only a small patch of opus caementicium floor with a geometric motif of white and black tesserae survived. This room probably belonged to another domus and appeared to be closed to the west and south by two walls, also robbed. The excavated structures can be given a preliminary date of between the 1st century B.C. and the early 1st century A.D.
