It feels odd to be agreeing with @Gain, but I don’t see how that could be true either. Chiang Mai as #3 as well. I didn’t look into what the index is supposed to mean though.
I saw another list earlier today saying that Taiwan had two of the top ten cultural attractions in the world or something like that. #6 was CKS Memorial Hall IIRC, but the list didn’t seem plausible enough for me to bother checking what the other one was.
Edit: I guess it was this list, but I saw a different article.
