A castle (cum castro) in Żywiec was first mentioned in 1467, as destroyed by an army, under Casimir IV Jagiellon's command against the House of Komorowski, with the Korczak Coat of Arms, recorded by Jan Długosz. However it is not certain whether it denoted the castle in the town or a fortifications on a nearby Grójec hill. Archaeological scrutiny dates the origins of the castle in the first half of the 15th century. A later expansion was constructed in 1567 by the House of Komorowski. Under the ownership and will of Jan Spytek Komorowski, during the castle's expansion a Renaissance style courtyard was built, which is still untouched in its current form.
Since 2005, the Old Castle in Żywiec hosts the City Museum in Żywiec. The Old Castle's permanent exhibition includes an ethnographical exhibition - which completes the Wooden Architecture Trail in the Silesian Voivodeship, in Poland.
Żywiec's Old Castle is encompassed by a 260,000 square metre landscape park, which was established initially in the 17th century.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
