Hotel Castel Badia / Sonnenburg: Adaptive Luxury in an Old Monastery
Hotel Castel Badia / Sonnenburg crowns a historic hilltop above Castelbadia, Italy, where null17 Architektur reworks an 11th-century Benedictine monastery into a new five-star hotel. The project retains the ensemble’s layered past while preparing 29 individual rooms, a spa in the former cells, and a herb garden revived from medieval sources. Guests move through a building that carries Roman traces, a 12th-century crypt, and contemporary interventions held in one careful, unified vision.
