The Geremia Fort was built by the military engineers of the Kingdom of Italy, towards the end of the 19th century, on the large eastern peak of Bric Geremia (819 m) from which it takes its name, forming a complex of fortifications that, together with the nearby Aresci Battery (now half-destroyed), was intended to control the Turchino Pass and the adjacent valleys.
The decision to build it was taken in order to better control the Apennine pass which, from the end of the 19th century onwards, took on great historical and commercial importance for the valleys of western Genoa and for Genoa itself. The two defensive constructions, surrounded by a considerable moat, were equipped with a telegraph and a military road, thus allowing rapid road and communication links.
Garrisoned until the First World War, the Aresci Battery was affected on 28 January 1914 by an explosion of the powder magazine, which not only caused the death of some soldiers but also damaged parts of the battery. Later abandoned, mainly due to the lack of war use, the battery’s guardhouse and the square in front of it, where the firing positions and barracks stood, are still visible today.
Fort Geremia, on the other hand, is a two-storey stone barracks in good structural condition despite its abandonment after the Second World War. According to detailed studies, the barracks could hold more than one hundred troops and the armament was composed of two 9 BR/Ret cannons and six 12 BR/Ret cannons, thus controlling the Turchino valley and the Stura and Vezzulla heights. The powder magazine, isolated by a ring-shaped cavity, was built inside Mount Geremia and even today a tunnel-corridor allows you to reach it from the barracks. At one end of the barracks there is a caponier with the purpose of controlling the entrance, the square in front and above all the access road to the fort.
Today, Forte Geremia is owned by the municipality of Masone, which, thanks to recent restoration and conservation work (completed in 2012), has transformed it into a visitor centre and equipped rest stop for the Beigua Regional Nature Park.
