It’s like Trigger’s Broom down in the London Mithraeum. The ancient Roman Temple of Mithras was discovered in the 1950s, moved about a bit, covered in crazy paving, moved into storage and then moved back a few metres from where they first found it, reassembled piece by piece each time. If you move a building from where it was built, is it still the same building? If you rebuild it, is it still itself? That’s one of the questions Korean artist Do Ho Suh is contending with upstairs, where he’s built his own recreation of an ancient temple: the long lost Sach’onwang-sa from the city of Gyeongju.
