M5 - La Prévôté 

A ruinous late 19th century watch-house sat above the cliffs when German forces arrived in 1940, being strategically placed by the Victorians to watch for an oncoming invasion. Clearly, the Germans were of the same mind, quickly constructing the three floored Mebstelle 5 in its place, tearing down the old ruins. The tower was painted with a granite pattern, perhaps imitating a ruined mill or loophole tower. The tower is perhaps the most unique of all army observation positions on the island, and clearly involving complex form-work to construct. While two floors served observation and accommodation, a basement served as accommodation and storage. All floors were accessed via rungs, with an escape shaft from the basement. The tower is sealed and derelict as of 2026.

It is worth noting that the dimensions of the tower are consistent with that of a standard MP tower, and the basement is likely built to Fortress standard. This supports the theory that while the plan to built a full MP tower here never materialized, the basement was cast, and the tower on top is actually a later addition by the army when it was handed to them by the Kriegsmarine.
