Starting from the Second World War, the recent history of the Castle is defined by a series of recovery of its ruins. A first cycle of work was undertaken in the 60s and, in about twenty years, it gave back the building to its completeness. This intervention recovered many parts that were completely ruined by centuries of neglect.
From 2003 on, every intervention has been supervised by the Superintendence for Architectural and Landscape Heritage for the Provinces of Turin, Asti , Cuneo , Biella and Vercelli, in order to maintain and preserve the stone evidences of the outer walls ( S-W sides ), the patrol paths on the ramparts and the battlements.
A preliminary consolidation of the surfaces, a subsequent cleaning operation and a final protection intervention have been provided in order to give back the material and aesthetic continuity of the whole building’s surfaces.
During the previous construction site, the southern part of the building was covered with huge stone slabs and strenghtened by a new plant for lightning protection.
In 2011 a study campaign has been started for the Castle’s Chapel, in preparation for a new restoration action. These historical studies, together with many stratigraphic tests on interior adornments, give evidence of a rich trace of a late-medieval decorative painting, covered by most recent decoration layers.This artistic heritage is totally unprecedented and may be discovered in the course of a forthcoming restoration.
