This has to be one of the easiest WHS to tick off your list if you only intend to view one or a few of the 33 Belgian sites + 23 French sites in this entry. However, it is quite a task to visit all of them since they are scattered all over both countries. I have visited 16 sites in total (14 in Belgium and 2 in France) and climbed most of the belfries where this was possible. My favourite one is that of Tournai, adorning the square below and the cathedral nearby (another WHS), closely followed by the belfries of Antwerp and Bruges for their architectural beauty and importance.
