The Saint Leonard's Church in Zoutleeuw stands on the former site of a Romanesque chapel erected in 1125 by Benedictines from Vlierbeek Abbey near Leuven. Construction of the present church began around 1231, and additions continued into the 16th century. Rendered mainly in the Gothic style, the building in its oldest parts shows traces of the Romanesque.
The two heavy square towers flanking the west facade are connected with each other by means of a gallery over the nave. The slender central tower, octagonal in cross-section, contains a carillon with 24 bells. Since 1999, this church with its towers has been part of a UNESCO World Heritage Site 'Belfries of Belgium and France'.
Few if any other medieval churches in Belgium remain in such an excellent state of preservation as St. Leonard's, which stayed clear of the widespread iconoclasm during the Protestant Reformation. It also survived the French Revolution intact, because three canons took an oath of allegiance to the French regime. The interior thus offers an authentic glimpse of how the churches of Brabant were furnished centuries ago.
References:The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
