First build as a hall without a transept in 1250, the church was changed during construction. In the style of French cathedrals, the central hall was high (38.5 metres) and held up by flying buttresses. The 125 metre high steeples were completed in 1350. The inside gives a grand perspective. See the Briefkapelle decorated with high lancets in the Gothic style and on the souther tower, the two bells that fell to earth during the 1942 bombings.
