The _corte_ of S. Ambrogio at Capiate di Olginate is an architectural complex constituted by several buildings constructed over time and ending with its present agricultural use. The medieval parts of the complex are listed, in particular the church of S. Nazaro, dated to the 8th-9th century, and the building known as the “tower”, which according to some studies was built in about the 12th century. During the last centuries, there have been occasional finds in the area. These include an incomplete gravestone with an inscription relating to the _cursus honorum_ of an unknown individual, datable to a time after the death and deification of the emperor Nerva (98 A.D.), and diverse architectural elements present inside the masonry. A project for the reclamation of the complex is underway which necessitates the creation of damp proofing and the putting into place of underground utilities. Therefore, the superintendency ordered the excavation of a number of trial trenches. Ten trenches were excavated both within the structure of the court and in adjacent fields belonging to the same proprietor. All trenches produced positive results, revealing both the remains of buildings constituted by walls of medium sized cobbles bonded with lime mortar and inhumation burials generically datable to the medieval period. None of the walls identified continues or integrates the present standing structures, rather, in some cases it was seen that the foundations of the latter rested on some of the elements uncovered by the excavations. Given the large number of structures found and their dispersion across the area under investigation, it was not possible to identify their form or function. Future work will lead to a better interpretation of the site.
