Mesocco Castle San Bernardino Castle Mesolcina Calanca The ruins of Mesocco Castle stand on top of an imposing rocky hill that rises steeply from the valley floor. This imposing fortress stands in the center of the valley, forcing the Moesa River into a wide bend in a narrow, impassable gorge, leaving only a narrow passage to the west. Mesocco Castle is protected on three sides by steep cliffs. Only to the northeast, on the upstream side of the valley, does the slope slope more gently. Climbing up the old access road to the castle from the north side, you first reach the Church of St. Maria del Castello and are already on the castle grounds, which were once surrounded by a defensive wall. The impressive ruins consist mainly of the remains of defensive works built in the last decades of the 15th century, i.e., during the final phase of the castle's life. Among them are numerous ruins from earlier eras, so that the castle's current appearance reveals its eventful history, which has its roots in the early Middle Ages.
