The Sint-Stevenskerk dominates Nijmegen's Grote Markt with its massive Gothic tower, but almost everything you see today was rebuilt after February 1944, when Allied bombing raids aimed at the German-held Waalbrug accidentally destroyed much of the medieval city centre. The church burned for three days. What was reconstructed in the 1950s and 60s closely follows the medieval forms — the proportions feel genuinely Gothic, not ersatz — but the rebuilding means the interior is lighter and less encrusted than older Dutch Gothic churches.
The tower can be climbed in summer for views over the city and the river. Inside, look for the carved choir stalls that survived the bombing and the modern stained glass, some of which takes WWII imagery as its subject. The church remains an active Protestant congregation; check times before arriving to avoid coinciding with services.
