Solivagant:
Interestingly, Ian only grants that most "Brutalist" of WHS (i.e Le Havre) 2** !
:) Just a quick note entirely off thread for this topic, but my views have softened a little on le Havre since I last visited, about 13 years ago now, and have become much more a fan of full brutalist architecture (lots of exposure to good examples on my daily commute have helped).
So I'm rather looking forward to returning to le Havre to give a re-evaluation, but my score stands from my previous visits.
And just being modern architecture doesn't necessarily mean it will be a winner for me, there are good and bad examples everywhere (I'm really not much of a fan of le Corbusier or his approach, though will defend his inscription) and visiting all of these different sites helps bring out my tastes.
Some of the sites in that category that I have enjoyed most, were ones that on paper I didn't think I would enjoy at all (
Casa Barragan,
Brasilia (for the broader residential plan), even
le Corbusier's Villa Savoye).
