Hoher Stein, Fortified tower in Anklam, Germany.

Hoher Stein is a cylindrical brick watchtower built in 1458, standing west of the B109 road southeast of Anklam. It has a crenellated parapet, an octagonal masonry helm, and several arrow slits. Originally surrounded by a moat, it rises on a small hill a few metres from the roadway.

A watchtower of the Anklam Landwehr was first mentioned in 1412, and the Hoher Stein itself was built in 1458 as a brick structure. It was one of four watchtowers guarding the approaches to the town, erected because of frequent raids by the Schwerin nobility. From its top a guard lit a fire on an iron pan to warn Anklam by smoke signal, since this part of the field could not be seen from the town's two church towers.

The tower shows how Anklam's residents protected their city over centuries and how important this defensive structure was to local identity. Today, visitors can understand what role such buildings played in the everyday life of a medieval town.

The tower stands a few metres west of the B109 road in the southeast of Anklam, outside the old town, so it is reached by car or on foot along the road rather than through city streets. The brick cylinder, crenellated parapet and octagonal helmet are best seen in daylight.

The tower's top held an iron pan where a guard lit a fire when enemies approached. Smoke signals warned Anklam because this part of the field could not be seen from the city's two church towers; the watchmen on the stone gate's parapet then looked for the signal.
