I can add to Dresden and Nuremberg. Both of them where nearly destroyed and rebuild. But the rebuild is not an exact rebuild. It is new and modern buildings.
But there are exceptions like the Frauenkirche in Dresden and alike buildings here in Nuremberg. They are almost exactly rebuild in the name of conserving heritage. Yes, they are also rebuild or even retrofitted with new things like electric and plumbing. But that doesn't mean they are new buildings.
