Sorry, that is not clear to me..
no buildings are within the historic center?
I can find Bercy and La Chapelle on this map, and I'm gathering the buildings are right at the edge abutting the historic center, and perhaps under the peripheral road?
If not, then I'm not by definition opposed myself, though I might be if I understood more what those peripheral areas look like, and why Parisians are against such building. (As you know, I've never been to Paris).
From the images in the article, now that I surmise those areas are on the periphery, the buildings seem outsized re what is presently there. So, assuming they go ahead with these, it seems it will precipitate a lot of change in the Paris skyline. I can see the Parisians point.
Hmm, La Phare isn't that close, is it?
Does that height limit that is being broached cover the entire periphery?
