Sechsschartenturm, heavy MG bunker, La Mare Mill, or 4-S WaKoFest, Wn La Mare Mill, consists of a sechsschartenturm (English: six-loophole turret) and a personnel bunker. The Organisation Todt built it to an Atlantic Wall standard on a commanding position near the demolished La Mare Mill during the Occupation of Jersey.

Sechsschartentürme turrets were common place along the Atlantic Wall and the Germans constructed nine in Jersey, but today only this and one other example at Mont Mathieu survive. The Channel Islands Occupation Society now operates the turret and bunker as a museum.
