Perhaps the most important national haven in Poland, the Wawel Cathedral has witnessed the coronation of a line of Polish monarchs and has also been the cradle of their tombs. This gothic, Roman Catholics church houses artefacts of absolute historical and cultural significance. With its silver coffins and crypts, murals and stained glass windows, the Wawel Cathedral is fascinating. The most mesmerizing of them all are the animal bones on the iron doors that are believed to have magical powers. Additionally the Sigismund Chapel on the inside is supposed to be the most beautiful Renaissance Chapel north of the Alps. For those interested, there is also a Wawel Cathedral Museum. Before exiting Wawel Hill, make sure you also visit the Dragon’s Den (a cave that is some 130 steps below) and the Thieves’ Tower for rather hackneyed tales of Wawel’s fabled dragon and brilliant views over the Vistula River. Shelling out 12PLN grants you entry into the Wawel Cathedral along with the tombs and the Sigismund Bell Tower with its 11 tonne bell. You could rent English audio guides for 7PLN if in case you are looking for a detailed tour. It is open from 9am to 5pm, Monday through Saturday. On Sundays, it opens at 9:30am. You would have to pay an additional 3PLN for the Dragon’s Den. Tickets for the Cathedral are available from opposite the main gate and for the Dragon’s Den, a coin-operated machine is located right outside the entrance of the cave.
