Ouvrage La Déa
Ouvrage La Déa is a military fortress, part of the Maginot Line's Alpine extension, at an elevation of 1.753m (5,751ft) above the sea level, located in the Alpes-Maritimes department in southeastern France.
The road to the fortres is gravel, rocky, tippy and bumpy at times. This is definitely not a Sunday drive. Drive with care as this is a mountain road with dangerous dropoffs. The road is usually impassable from October to June (weather permitting). Avoid driving in this area if unpaved mountain roads aren't your strong point. Stay away if you're scared of heights. The fortress, also known as the Petit Ouvrage de la baisse de la Déa, was built in 1934.
