Gotcha.
Don’t know exactly what they intend on doing with those columns and Ten Commandments in stone though. Germans like to avoid the topic so I’m guessing they won’t do anything, but would probably let the local synagogue have those things if they want them.
As an aside, in Munich I was taking a tour and we passed a large park with a pond and a very large hill that snaked a mile or two. It was covered in trees and walking paths. The tour guide told us it was the rubble from the WWII bombings that was unusable to rebuild!
