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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
