Muzeum Towarzystwa Ziemi Kozielskiej w Kędzierzynie-Koźlu

Set in what remains of the castle complex in Koźle, this museum is split into four displays. The archaeological one shows finds from digs in 1990–1992, the historical one tells the story of the town and its fortress in the 18th and 19th centuries, and the tower cellars hold an ethnographic exhibition of everyday objects. The art display has old furniture, clocks and paintings, including a copy of Kobell's Siege of Koźle from 1807; the original hangs in Munich.
