My hometown had a castle on a hill that was, as the story went, shipped over brick by brick from Europe when it was inherited by someone who was rather pleased to suddenly have a castle, but not-so pleased at it not being in California. True or not, it makes for a good story, and I suppose it's not impossible.
But I can't imagine the current Ul'dah being architecturally identical to the original, either way. For one thing, the engineering is far too modern.
