The eighteenth-century grand-ducal palace, now converted into a hotel, was until the last century the hunting lodge of the Lorraine family. The command of the local forestry station, as in Camaldoli and Badia Prataglia, houses a naturalistic museum open on request. A short distance away, a columnar trunk of silver fir lying on the ground is a testimony to the majesty and great heritage of the Campigna forest. A large part of the head of the valley of the Bidente di Campigna is covered by the forest of fir and beech which, near the ridge, gives way to the pure beech forest. In 1976, on the basis of a resolution of the Council of Europe, the whole area was recognised as a biogenetic nature reserve. The aim of the reserve is to preserve a highly representative strip of the Apennine mountain landscape and to protect the precious heritage of biological, floristic and faunal diversity that it preserves.
