Stunning building: former neo-Gothic spinning mill with turrets, perfectly restored. It houses a cultural foundation. It is very beautiful to see from a distance, but it is located at a fairly busy roundabout - viewing from a distance requires taking some risks. However, once you reach the center of the roundabout, it works as a life preserver, and you can have fun taking photos.

Porta Bolleris, or Boulera, is what remains of the majesty of the medieval village of Roccasparvera. Right under its arch, for centuries, goods and people have passed to and from nearby France. Of the Castle now nothing remains, destroyed by time and by countless border wars.

Roccasparvera has been an important lookout at the entrance to the valley for centuries. In medieval times, its village included four fortresses with high walls with watchtowers and a bridge that allowed entry to the town. Traces of these structures remain in the Porta Bolleris or Bourela, an ancient tower built in the 15th century through which goods and men passed to and from France and which was occasionally used as a residence for the Bolleris family, from which the tower takes its name. The gate extends just outside the walls of the town in the direction of the upper valley. Next to the ruins of this ancient fortification, there is a dense network of underground tunnels that opened escape routes and water supplies in the event of a siege or danger. Some paths lead to the ruins where the stone walls have been cleaned, allowing us to reconstruct the plan and imagine what they looked like.

Built between 1676 and 1678, it is the oldest remaining silk factory in Europe, among the few in Italy to have been recovered for museum and exhibition purposes. Today it is an irreplaceable witness of this recent past and from a silk factory it has been transformed into a cultural factory. It was later used as a barracks between 1939 and 1943 and today is the Museum of the Piedmontese silk factory. In the 1990s, the Council of Europe defined the Filatoio Rosso as "the most important historical-cultural monument of industrial archeology in Piedmont". The awareness that the Filatoio was a precious asset to be preserved gradually took hold. Today it houses, in addition to temporary art exhibitions, the permanent Piedmontese Silk Factory Museum, with the aim of enhancing not only the building, but an entire territory, becoming a sort of bulwark of Piedmontese historical-economic memory.
