The Observatory Houses project is an initiative led by the Italian Exhibition Group and the Italian government to repurpose the medieval fortress of Roccascalegna as a sustainable and exclusive observatory house model for astronomical tourism. The project aims to create a place for spirituality and meditation that allows visitors to experience the beauty and mystery of the night sky in a unique and remote setting. To achieve this, designers will need to create an architectural intervention that enhances the natural beauty of the site and provides a symbol destination for those seeking to escape their everyday routine and connect with the ancient and wild. The observatory houses will provide a one-of-a-kind experience for those who want to sleep under the stars and marvel at the movements of the planets and shooting stars.
