Montecalvo Fortress in Acquasanta Terme

History of the Montecalvo Fortress

The fortress arose in the period of incastellamento, when ridge routes replaced the Roman-era valley-floor routes, such as the Via Salaria along the Tronto valley. It stands on the watershed between the Tronto and the Castellano. In the 12th century it was fortified: the Castellano separated the Papal States from the Kingdom of Naples, and Castel Manfrino was nearby.

The territory of Montecalvo, which became a sindicato (a rural district) around the 14th century within the area of the Free Commune of Ascoli, remained an independent municipality until the birth of the Kingdom of Italy. On January 1, 1866 it was merged with Acquasanta. Rugged mountains, difficult access and its border position encouraged banditry. In the 16th century the crackdown also hit the fortress, which was torn down.

What to see at the Montecalvo Fortress

Only a few ruins of the fortress remain, completely abandoned. Brambles and weeds cover the ruins and a television antenna sticks out among the remains. The reason to visit is mainly the place itself: from near the fortress the view opens over the Castellano valley, a patchwork of woods and clearings. Along the nearby trails are chestnut groves, beech woods and meadows.

How to visit the Montecalvo Fortress

The ruins are reached on foot. One route starts from a parking area further down. From there a trail crosses a chestnut wood and passes below the fortress, up to a signposted junction. A short detour to the right leads to the remains, but the stretch is not easy and requires climbing a short rock face.

The fortress is also on the hike from San Paolo to San Martino, by way of the Macera della Morte. Up to the summit of the Macera della Morte the route is 11.6 km one way, of medium difficulty, and recommended from March to November. It follows a stretch of the Sentiero Italia CAI. Check the weather before setting out.

Where the Montecalvo Fortress is located

The fortress overlooks San Martino, in the southern part of the territory of Acquasanta Terme. San Martino can be reached only by winding roads starting from the main town and from Valle Castellana. From the Salaria, at Acquasanta, follow the signs for Paggese and then for San Martino.

Around the Montecalvo Fortress

Further down the Castellano, near the Lago di Talvacchia, is the hamlet of Rocca Monte Calvo, not to be confused with the fortress. Along the trails that reach it, terraces and dry-stone walls can be seen. Fortification enthusiasts can continue to Castel di Luco (Acquasanta Terme), in the same municipality.
