The north-eastern part of this 17th century monastery has been donated by the Cappucine monks for the creation of a centre for the disabled. During the conversion work structures relating to the earlier phases of the building came to light. To the north-east of the cloister, the remains of a wall belonging to the original monastery was found. This had been demolished to enlarge the sacristy to the west, an operation which reduced the size of the cloister garden. A ramp has been put in between the sacristy and the church. Previous work, for the installation of heating pipes, had already intercepted and partially destroyed the corner of a structure which was part of the church wall. The church may originally have had a much smaller apse than the present one. Outside the wall was a roughly made cobblestone pavement. Subsequently, a small trench was opened, for telephone and electricity cables, running along the west and south sides of the church, as far as the main entrance in via Roncato. The southern stretch of this trench was full of modern debris, the result of recent restoration work. It was, however, noted that the church and the northern part of the monastery were built upon a coarse fluvioglacial substratum, which provides a stable and well drained base. As the trench travelled south, approaching the vegetable gardens, the large river stones gave way to alluvial sands which overlay deposits of fine, sterile gravel. In the upper levels the sands were light in colour and free of archaeological material. Lower down they contained more organic material and fragments of 17th century pottery. A drainage channel also came to light which belonged to the same phase as the lower level. It is probable that both levels belonged to the original monastery building. No traces were found of remains that pre-date the monastery, even though local history records that it was built on the site of some earlier houses and the church of Santa Caterina.
