St-Salvatorskathedraal

Stacked sub-towers top the massive central tower of 13th-century St Saviour’s Cathedral. In daylight, the construction looks somewhat dour, but once floodlit, it takes on a mesmerising quality. The cathedral’s interior is vast but feels oddly plain, despite a selection of antique tapestries. Beneath the tower, a glass floor reveals some painted graves, and there’s a passingly interesting treasury displaying 15th-century brasses and a 1559 triptych by Dirk Bouts. Look out for the summer organ concerts.
