Owner of the oldest of the three great spires that dominate the pedestrianized heart of Ghent, the St. Nicholas’ Church (Sint-Nik­laas­kerk) was constructed between the 13th and 15th centuries in an eye-catching mixture of Romanesque and Flemish Gothic architectural styles. Built of Tournai limestone, its lovely exterior is adorned with flying buttresses and spiky spires as well as an imposing central tower; all this grandeur was paid for by Ghent’s wealthy medieval merchants to signal their wealth to the rival Flanders trading cities of Bruges and Antwerp. It’s probably more beautiful inside than out, but nevertheless all eyes lead to the Baroque high altar with its twisted side columns, floodlit through stained-glass windows high above. The church is currently under restoration but faint traces of fresco can still be seen on the supporting pillars of the nave. For the best view of St Nicholas’s flying buttresses, head for the viewing platform of the Belfry a few steps away.
