Mount Musinè is the easternmost mountain of the long ridge which, starting from Rocciamelone, divides the valleys of Susa and Lanzo. Its main summit has a subsummit called Truc dell'Eremita, and is surrounded by several minor hills. To the east on a 535 m high hill stands Saint Abaco's sanctuary, and to the northeast on Monte Calvo, 551 m high, there is a Via Crucis leading to a chapel. Mount Musinè is connected to the neighbouring Mount Curto by a broad wooded ridge, the lowest point of which is the Colle della Bassetta. Mount Musinè's summit is a tripoint at which the borders of the municipalities of Caselette, Almese and Val della Torre meet.
A number of prehistoric and protohistoricarchaeological sites have been discovered in the area. These include traces of a hut dating to the early Bronze Age found in Caselette, and several finds from the late Iron Age in the vicinity of Almese. Two Roman buildings from the imperial period are located near the mountain: a villa rustica in Caselette and a large residential villa in Almese. A local tradition states that it was near Mount Musinè that the emperor Constantine I saw a flaming cross and the wordsIn hoc signo vinces shortly before the Battle of Turin against his rival Maxentius, which he won . The battle was historically important because with this victory emperor Constantine the Great was able to impose the Christian religion in the Roman empire and to eliminate paganism. In 1901 a 15 m high cross was built on the top of the mountain using reinforced concrete. On the northeastern slopes of Mount Musinè several magnesite quarries were active between 1875 and the Second World War.
Several encounters with UFOs have been reported around the mountain from the 1970s onward. Quite well known is the case of December 8, 1978, when two young hikers walking on the slopes of the Musinè saw a bright light; one of them, after approaching it, temporarily disappeared. His mate, with the help of some passers-by, searched for him and after a while found his friend in a state of shock and with a noticeable scald on one leg. After regaining consciousness the young man he reported having seen an elongated vehicle and that some strangely shaped beings descended from it, touching and hefting him. Both the young hikers suffered from conjunctivitis for some time.
