Haus Demmin

Haus Demmin is a castle ruin on an island at the meeting point of the Tollense and Peene Rivers in Demmin, with sections of fortification walls still visible today. The grounds contain a main fortress area and an outer defensive section.

The fortress was founded in 1127 as a Pomeranian stronghold and served as a residence for the Pomerania-Demmin dynasty until the death of Wartislaw III in 1264. Swedish and Imperial forces inflicted heavy damage during the Thirty Years War, demolishing its defensive tower in 1648.

The ruins display medieval brick architecture typical of the region, with a distinctive round keep built in the 1200s. Visitors can still see how the construction reflects the early defense strategies of the Pomeranian rulers.

The site sits centrally in Demmin on an island and is easily accessible from the riverbank. Paths across the ruins can become muddy in wet weather, so sturdy footwear is advisable.

The island where the fortress stands offered natural protection from the meeting point of two rivers, a strategic placement the early builders used skillfully. This geographic feature made it a difficult stronghold to besiege in its day.
