Castel del Rio is a small mountain village, located along the green Santerno Valley. On the higher slopes, woods and chestnut trees are the stars.
The center of the village bears the marks of the Alidosi Family's dominion, with the Alidosi Palace and Alidosi Bridge.
The small town offers the chance to enjoy nature: chestnuts trees and their fruit (Marroni IGP of Castel del Rio) are protected by a prestigious brand, regulating the production.
The War and Gothic Line Museum offers to the visitor an interesting look at the World Wars, through the recovery of military equipment and weapons, found by the locals in the nearby fighting areas. A wide collection of arms and uniforms is housed here and a small section, "Animal Tower", is dedicated to local fauna.
The Alidosi Bridge is a unique example of a humpback bridge of particular greatness: it has stood over the Santerno River since 1499.
The perfect season to visit Castel del Rio is autumn: the town comes to life with the Chestnut Fest and its food stands, preparing chestnut delicacies. It is also possibile to take part in the chestnut harvest in some areas, but not everywhere.
In summer time, the village offers the chance to escape from the heat: the riverside area, right under Alidosi Bridge, is perfect for resting and bathing in the river.
