Poland's national sanctuary with a 1000-year-old history, this monumental edifice was the coronation site of Polish monarchs. Arguably the most interesting place in the whole country, with the adjacent Wawel Castle being a close second, its preserved 14th-century walls shelter a great variety of exquisite art: Gothic, Renaissance, Baroque, Classicist and Modern. It is the place of burial of most Polish royalty as well as other national heroes, poets, saints and countless Catholic Bishops of Krakow. The interments are all in the cathedral which actually is a part of the castle. The center of the nave has a mausoleum (from 1630) for Poland's Patron Saint, Stanislaus, an 11th-century Krakow bishop murdered by King Boleslaw II. The martyr's silver coffin is adorned with 12 relief scenes from his life and miracles. Marble tombs of four 17th-century Krakow prelates neighbor it. Near the main entrance of the cathedral, between pillars on the right side of the nave, there is the 15th-century sarcophagus of King Wladislaw II Jagiello, made of red Hungarian marble, and at the end of the north aisle there is the mid-14th-century sandstone sarcophagus, the cathedral‚s oldest, of Wladislaw I. His son, Casimir III the Great, rests on the other side of the high altar, across the nave, at the end of the south aisle in a red marble sarcophagus ranking among Europe's finest sculptures of the period. The middle of the south aisle has the sarcophagus of a 14th century queen, created in her memory in 1902 and carved in white marble. Eighteen special chapels full of art treasures surround Wawel Cathedral. The Sigmund Chapel in white contrasts the exquisite Baroque of the black marble Vasa Chapel. The Chapel of the Holy Cross has Russian murals from 1470 and the splendid marble sarcophagus from 1492 of King Casimir IV Jagiello by Veit Stoss. That chapel also has two outstanding late-Gothic triptychs by 15th-century Krakow painters, an imposing late-Baroque tomb of a bishop and fine stained-glass widows from the turn of the 20th century.
