Centre of the upper Trebbia Valley, it is located in a basin dominated by Mount Prelà and rich in spring waters that give rise to the Laccio stream, a spring branch of the Scrivia. The village boasts ancient Roman origins with the name Patrania. In the Middle Ages it was the seat of the ancient Abbey of the same name, founded before the year 1000 and the centre of evangelisation of the entire valley. The Castle, built close to the village and whose remains are still visible, testifies to the presence of a feud for whose possession the Malaspina, Fieschi and Doria families succeeded one another. In addition to some typical gastronomic products such as 'canestrelli', Torriglia is known for its natural and scenic attractions that make it a popular resort. Of particular note are the rural village of Pentema, perfectly preserved in its original architectural features, where an evocative nativity scene is set up every year, and Lake Brugneto, an artificial basin created in 1959 by submerging the villages of Casoni and Frinti. The aforementioned hamlet is also part of the Antola Regional Natural Park: one of the most enchanting areas of the Apennines and the Ligurian hinterland, thanks to the extraordinary panorama of the 1600 m Mount Antola and the activities of the nearby Brugneto Lake.
