This town is of considerable strategic importance as a defence town and control of impassible but shorter route between Umbria and the Adriatic. The town currently conserves the structure of the ancient medieval castle town with its white and pink stone walls which still today surround the town and have two entrance gates, Porta Santa, the main gate and Porta di Mancione. Each year in September the town holds the medieval event called Palio della Rocca (the rock race) in which one of the oldest games of the medieval and Renaissance eras takes place, the goose race. Not far from the centre is the paleocristian crypt of San Biagio of the 4th and 5th century, the oldest in the Marches and still preserving its original structure.
Immersed in larch, oak and hazel woods and overlooked by the Catria massif, stands the well-known Camaldolese Hermitage of Avellana. A walk along a short footpath will allow you to admire the botanic garden of Fonte Avellana: a woody strip in which numerous age-old trees are gathered (ash, maples, lime trees, hornbeam, beech trees and chestnut trees) including the famous “Tasso di Fonte Avellana” (the yew of Fonte Avellana) one of the biggest trees in Italy.
