Royal Archcathedral Basilica of Saints Stanislaus and Wenceslaus

The Wawel Cathedral, formally titled the Archcathedral Basilica of Saint Stanislaus and Saint Wenceslaus, is a Catholic cathedral situated on Wawel Hill in Kraków, Poland. Nearly 1000 years old, it is part of the Wawel Castle Complex and is a national sanctuary which served as the coronation site of Polish monarchs.

The current Gothic cathedral is the third edifice on this site; the first was constructed and destroyed in the 11th century and the second one, constructed in the 12th century, was destroyed by a fire in 1305. The construction of the existing church began in the 14th century on the orders of Bishop Nanker. Over time, the building was expanded by successive rulers resulting in its versatile and eclectic architectural composition.
