​​Pleinmont Observation Tower: Hitler’s Atlantic Wall​

​​Up to 7,0000 forced workers (working for the Organisation Todt) were brought to Guernsey from Europe and used to build most of the fortifications there between the years 1941 and 1943. Organisation Todt was a civil and military engineering group named after its founder, Fritz Todt, an engineer and senior Nazi figure.

The tower was designed to turn the Channel Islands into impenetrable strongholds and formed part of Hitler’s Atlantic Wall. Inside there are detailed descriptions and maps of the Islands' military defences, as well as a mounted machine gun and field telephones. When the wind isn’t too strong, visitors can climb up the ladder to the roof for views of the cliffs and countryside.

The original rangefinders are still onsite and in working order, and there is also access to a battery dolmen gun-site nearby.

​The tower is open on Wednesdays and Sundays only, from 14:00 to 16:30. Last admission is 16:00.
