As tragic as this is. I think they should plant a new tree in the same location.

I know it won't be the same, it won't heal the wound, at least not for hundreds of years, if ever. But it's just how society and the world is. Great things are made and appreciated, treasured even, and endure for a while, then they are broken by something, one way or another. And you can't undo that damage, but you can start over and build again. And that's all you can ever do. And although it may not seem like much now, there can perhaps still be greatness in the future again if we start to build it now. That greatness may not be exactly the same as the greatness of old, but it can be great in its own way.
