LeMonde has an article on the renovation of Buren's columns called les deux plateaux. They have just been re-inaugurated after a little over a year's worth of restoration work. Maybe it's just an everyday curse visited on very public art in France, but the cour had been allowed to deteriorate into a real mess. I can't recall when I last saw the water on. I was never much of a fan of the project but the gardens and the cour are, to me at least, one of the ultimate urban ensembles and to see one part in such disrepair was a disappointment.
