Hi all,
Indeed France and Belgium both have many of these monuments, but I believe that in France a lot of these wont be monument historique. Due to the fact that most of their monuments are really really old and special. (there are ca 60.000 monuments in France but there are also that number in both Flanders and the Netherlands, this means that to become a monument is easier in the latter two and therefore less special buildings are monuments). The same issue might hold for Wallonie. For other countries I don't know how the situation is, so this point is a little bit focused on only some of the countries.
So there might be a lot of these monuments (in every small city) but a lot of them wont be eligible for the local contest, how to deal with that?
Mvg,
Bas
