Down there you can see the remains of a stone foundation that forms the western corner of a guardhouse that was built in the late 17th century, called the Arrest/arresten. It consisted of five rooms, one of which was inhabited by the guard.

Two rooms are built in stone for “worse prisoners”, so-called “Finkan” and two rooms are built of timber for “better prisoners”. What is meant by better prisoners is unclear, but perhaps it is criminals who have committed milder crimes, It is also possible that the fortress’s crew, such as drunken soldiers or inattentive guards, may be detained for a short time as a form of disciplinary action.
