It’s a beloved space, and was sadly damaged when the WTC came down. I’ve been mourning it. There’s a longish piece on it with before-and-after illustrations in my weblog of Wednesday, September 19, 2001, archived here. The news this morning is that they’re fixing it, and from the sound of things are going to considerable effort to make it what it was before. Of course it can’t quite be that, ever again; what was a peaceful area within a much larger complex is now likely to be a pass-through from the esplanade to the empty space beyond.
