The Kwidzyn Gate is a preserved showcase within the city's defensive walls. Gothic, five-storey building from the first half of the 14th century.
In the 16th century, a hospital for the poor was built next to the Kwidzyn Gate, hence the alternative name of the gate to Szpitalna. Rebuilt many times, served as the entrance gate, later it was a prison. Since 1908, it played the role of a water tower with a characteristic dome-shaped water tank. It has been restored to its former appearance.
The tower hosts the exhibition of the collection of Werner Zebrowski (born in 1923) – who lived in Riesenburg until 1945 – gifts presented to the city (paintings, appliances, postcards, maps, plans, photographs, books, etc.) and a model of the former castle. The top floors of the building are currently the home of the Werner Zebrowski Exhibition Hall, which hosts paintings and graphics of pre-war Prabuty. This exceptional resource takes the tourists on a sentimental journey into the past.
During the summer, the top floor hosts a tourist information point.
