Benoît,
That would be wonderful, and if you have any more info on the Brussels and Wallonian heritage institutions in the fr wiki, let me know and I will translate those in the en wiki also.
I am also missing a wiki page on the organization for protection of French monuments, and the organization of the European Heritage Days in France seems to have a problem with their website:
If you have any info on them that I could use in a wiki page, that would be great!
