The fort lies on the southern ring dike of De Beemster polder. The North Holland Canal runs behind the fort and the dike. An inundation lock for De Beemster lies east of the fort. The purpose of the fort was the closure and defense of the accesses form by the Middenweg and the Zuiddijk. The original situation around the fort has been preserved: open polder landscape outside the Defense Line and the dike and the canal inside the Defense Line.
