Wawel Royal Castle is the historic seat of Polish kings and a symbol of Polish statehood since the 11th century. Perched on Wawel Hill overlooking the Vistula River, it blends Gothic and Renaissance architecture in a vast complex housing several museums and exhibitions. The State Rooms display a unique collection of Flemish tapestries, while separate exhibitions showcase arms and armor and the Crown Treasury. Walking the castle courtyards is free and offers magnificent views of Krakow and the river. Each exhibition requires a separate ticket with limited daily visitors, so advance online booking is strongly recommended especially in summer
