Monte Gran Costa is a high mountain pass at an elevation of 2.615m (8,579ft) above the sea level, located in the Province of Turin in the Italian region Piedmont. It's one of the highest roads in Italy.
The road to the summit is called Strada dell’Assietta. It’s gravel, and impassable in winters. With such a high summit altitude the road can be closed anytime due to snowfalls. The zone is prone to heavy mist and can be dangerous in low visibility conditions. At the summit there’s a military fortress called Batteria Monte Gran Costa. It was built in the late 1800’s and could accommodate 200 soldiers. The last 1.3km of the road are closed to vehicles by a barrier.
