Holding its own against the imposing Domtoren across the square, this grand Gothic cathedral was built during the 13th and 14th centuries and designed in the style of Tournai Cathedral in Belgium. It has five chapels radiating around the ambulatory of the chancel, as well as a number of funerary monuments, including that of a 14th-century bishop. The entire space between the tower and the Domkerk was originally occupied by the nave of the huge cathedral, which was destroyed in a freak tornado in 1674 and not rebuilt. Many other buildings were damaged, and the exhibition inside Domkerk shows interesting before-and-after sketches. Today only the chancel and tower remain, separated by an open space, now a sunny square edged by a road. Behind the chancel is the Pandhof, a 15th-century cloister with a formal herb garden with medicinal herbs, replanted in the 1960s. If you're lucky you'll come upon classical musicians, making the most of the wondrous acoustics. A free concert is held every Saturday at 3:30.
