Radar Exploitation Bunker by the Semaphore & then the Generator bunker. In front was a base for a Fu.MO 2 (FuMG Gema NR.g.236type 40a). A view back at the semaphore with the radar bunker and to its right the place the radar would have been placed. I have cut and pasted a Seetakt Gema radar scanner onto the picture to show what it may have looked like.

The view from the Pointe.
The Brittany coastline is very varied and beautiful, here with with cliffs, small coves, fishing ports and fine sandy beaches.

Another item that was also here was a Horchgerät - Listening device. The operators scanned the sky just as radar did later on and when they picked up the sound of aircraft engines, they tracked them and notified HQ of the Flak group and alerts were sent out, sirens would be sounded. It worked but was not as accurate as radars.
