In October 1939, the first contracts for the construction of the bunkers of the Line are signed with the civil engineers.
The bunker "Villa Rose" is one of the last elements of the fortified line in the direction of the Léman. It protects the Route Suisse, main road axe between Geneva and Bern in 1940. This very busy route was the main idea for the bunker camouflage.
The Combles premises, built for the camouflage, was fitted out to station soldiers (infantry). Today it has been converted into a ‘soldier’s canteen.
The building is made entirely of reinforced concrete and the walls are 2,5 m thick. The slits are reinforced by 10cm steel plates.
With the reform of "Armée 95" and the dissolution off the br fr 1, the bunker lost its military value. It was subsequently bought by the Association of the Promenthouse Fortified Line, restored to its original 1940/1945 look and rearmed.
The line as well as its bunkers was classified in Note 2 as part of the inventory of historic monuments of the Canton of Vaud and by the Swiss Confederation.
