Maybe this is it. Rebuilt-from-scratch temples have name continuity. To me, traditions and names are no less real than material things.

Edit: e.g. I lived in Suwon, where Samsung Electronics is headquartered. From historical records, we know it was also called Suwon in the 8th century, more than 1000 years ago. I think this sense of wonder is no less real than touching of 1000 years old artifacts.
