Anton had moved a huge magical building to another location once before.
Back then, he had used the Guardian Knight Charm, invented jointly by Dumbledore and Grindelwald, to turn the earth into a giant knight that carried Hogwarts School and walked into the depths of the North Sea overnight. (Chapter 891)
