The installation is located on a hiking trail and from the outside there is not much to see. The entrance is disguised as a water reservoir. The special feature of this minethrower is, that it was not installed as a monobloc but in a tunnel system. The guns and the entrance are only 45 m apart as shown on the sketch, but the access leads first far under the hill and then right again to the outside till the knoll. The other parts such as ammunition, technics and accommodation are also decentralized under the hill, connected with tunnels.
