26. Yes I wanted to add that too, the tax office doesn't particularly bother me, but the Hôtel Rigo is really a pity. Though in the local 'Mosan' style, it was not considered valueble because it was a "fake" from 1918
Yes, that's a pity, it's destroyed now.
The argument they gave, that it's not valuable because not old enough , seems to me the weirdest argument ever; since a lot of Flemish architecture in for ex, Ypres or Leuven are post-WWII rebuilding/restoration, that doesn't make them less valuable. Tourists from all over the world still visit those places. Sounds more like an excuse.
And the Mosan architecture is too rare as it's not well preserved, ironically you'd have to go to Maastricht to observe good examples of it.
