WAWEL ROYAL CASTLE - KRAKOW, POLAND
Things began to get into gear in 1138, when Krakow became the main royal seat. However, it was during the reign of Kazimierz the Great (1333-70) that the castle was truly born. A fire in 1499 destroyed much of this, yet also paved the way for Krakow's first taste of the Renaissance. It was then that the stunning courtyard was built, a design that started a long-lasting fashion in Poland.
