During the 2017 campaign, a trench was opened (25 × 20 m) in the area of Ghiacciaia where between 2012 and 2015 Venice University carried out an intensive survey and a first trench was dug in 2016. The area is situated in the northern part of the ancient settlement of Altinum, just east of the monumental centre of the Roman city, where the forum, basilica, theatre, and odeon stood. The excavation explored the structures and rooms in the residential quarter, already uncovered in 2016. Several rooms emerged that seemed to belong to at least two domus, separated by a narrow road paved with large blocks of trachyte, which probably covered a cloaca. This structure had been robbed, apart from a small section where the brick floor and a lateral parapet made of stone blocks. At least two different chronological phases were identified for the domus situated east of the cloaca. The phases were documented by two overlying floors in one of the rooms: a patch of opus caementicium with a geometric motif in white and black tesserae was covered by a new floor surface attested by a level of fine gravel mixed with cement mortar on a make-up of stone chippings. At least two other rooms belonged to this domus, in one of which the floor make-up of cement mortar was preserved. The floor surface itself was probably made of marble slabs of which the regular impressions are visible.

At least four rooms belonging to another domus were identified west of the cloaca. In two rooms, the fragmentary remains of the cement mortar floor make-up were preserved.
All of the foundations had been robbed in the late antique period.
A preliminary date of between the 1st century B.C. and 1st century A.D. can be attributed to the structures.
