I thought the Sagrada Familia looked better when it was unfinished. Now it's painted, it looks like something halfway between a particularly elaborate Christmas cake and a Terry Pratchett cover from the 1990s.
Surely it still isn't finished? I thought it was expected to be finished in 2026. Do you have any urls showing the current state?
The Sagrada Familia is a marvel, and deserves to be finished, but it was somehow magical to be there while it was (long-windedly) being built, worked on by skilled artisans probably not too different from someone working on the cathedral in my own home town in the 1090s.
There are quite a few to choose from: Ely, Durham, Canterbury, Winchester, etc., and of course others around Europe.
