Muzeum im. Wojciecha Kętrzyńskiego w Kętrzynie

A museum on the history of Kętrzyn and its surroundings, housed since 1967 in the rebuilt castle. The ground floor shows militaria, including armour, helmets and edged weapons, along with a heraldic cartouche from the Arklity palace and decorations from nearby residences. The collection began with heritage objects rescued from local churches, castles and palaces just after the war.
