The project defines architectural, structural and engineering solutions for overcoming architectural barriers, making part of the State Archive seat of Termini Imerese available and usable by all. Compatibly with safeguarding the historical and artistic character of the building, the works make the main spaces of the archive accessible. In particular, the interventions within the chapel of the former Jesuit convent reconfigure the continuity of the perimeter walls, improving the perception of the original spatiality.
