Observation tower
Initially a brick skeleton of the lookout tower was the chimney of the former boiler house. It was 80 meters high. In the 1950s a water tank with a capacity of 300 thousand liters was installed on the skeleton of the chimney. The water tower provided drinking water to the nearest neighborhood until 1995. The building was converted into the vantage point and handed over for visiting on 1 January 2008.
