Mariendom
This cathedral's Romanesque origins (foundations can be seen in the crypt) are best preserved in the choir's glorious stained-glass windows and beautifully carved stalls, and its biggest bell, the Gloriosa, is the largest free-swinging medieval bell in the world. Cast in 1497, it took three years to install in the tallest of the three sharply pointed towers, painstakingly lifted inch by inch with wooden wedges. No chances are taken with this 2-ton treasure; its deep boom resonates only on special occasions, such as Christmas and New Year's. The Mariendom is reached by way of a broad staircase from the expansive Cathedral Square.
