The main water tank was located in the characteristic dome. The tank designed by engineer Otto Intze was made of zinc plate and could house 200 m³ of water. This Water Tower supplied the citizens with running water till 1996. After the reconstruction of the water supply system a local businessman Mr. Henryk Górny bought it and transformed into a unique tourist attraction. A modern viewing terrace was added to the dome (it could be reached both with 129 steps and with a lift). In the Water Tower are also located a cozy cafe and a local museum, with a small collection of local historic photographs and documents. The Tower has also unique two crests above the entrance: Mazurian and cities, differencing it from technically similar buildings in the old East Prussia.
