Fortress on Oder River Island - Historic property for various uses

This property includes a former fortress building from around 1750, part of the eastern defence line of Koźle Fortress. Built in exposed brick on Ostrówek Island in the Oder River, close to Kędzierzyn-Koźle’s old town. 

The building, known as the “Redita na Ostrówku,” has a semicircular plan with a half-round projection at its centre. The ground floor features strong brick vaults and horizontal gun slits. In the 19th century, the building was converted for residential use, with an extension added in 1875. 

The plot is about 2,500 m² and includes: 

• The main building with around 800 m² (three full floors plus an attic suitable for conversion, 32 rooms). It can be divided into several independent apartments (including duplexes), used as a residence, or for hotel or restaurant purposes.
• Two outbuildings: a former garage and a small building with a barbecue area.

Planning permission and a heritage renovation permit are in place. The current plan is for 12 one-room micro-apartments and three two-room apartments. Some construction work has already started. Other uses are also possible.
