The second campaign at the Canonica di San Niccolò took place between the 30th August and 29th October 2010.
The investigations continued in the area of the church, cloister, the two buildings and the external area in an attempt to investigate the site’s various phases, which had only been partially identified by a study of the standing remains. At the end of the second campaign, the layout and structures uncovered indicated the existence of phases predating those attested in the documentary sources. Throughout the life of the complex, the main buildings maintained the original positions due to the close connection with the mining resources. Thanks to the reconstruction of the spaces for the period investigated by the excavations (12th to 13th century), a clear division was noted between the central nucleus, the Canonica di San Niccolò, the ecclesiastical settlement itself, and an external craft-working area, adjacent to the site but physically separated from it by the cloister enclosure wall.

The activities undertaken in this period in the buildings, in particular in the room bordering the cloister to the east and in the only covered room in the external area, provided more information. In both cases, the activities involved the working of minerals extracted from the surrounding mines. In fact, the production structures excavated in 2010 in the external craft-working area date to this period, in particular a furnace for the reduction of lead and other structures built in brick and clay, including a number of small clay-lined channels, one of which similar to those excavated inside the foundry building.
