Built in 1905 as a Palace for Kaiser Wilhelm II, Zamek is now a cultural centre with theatre and cinema. In the basement the 1956 Uprising Museum is based. Several cafes including an Irish pub "The Dubliner" is on site. The gardens hold the monument to the victims of Katyn and Siberia along with other public works of art. Certainly worth a visit, other important historic civic buildings and sculptures are also around this immediate area.
