The Jagiellonian tapestries, are a collection of tapestries woven in the Netherlands and Flanders, which originally consisted of 365 pieces assembled by the Jagiellons to decorate the interiors of the royal Wawel Castle in Kraków, Poland. The collection is also collectively known as the Wawel Arrasses, as the majority of the preserved fabrics are in the possession of the Wawel Castle Museum and the French city of Arras, which was once a manufacturing centre of this kind of wall decoration in the beginning of the 16th century. The works became state property of the Crown of the Kingdom of Poland according to the will of Sigismund II Augustus.
