If the works of Antonio Gaudi are an answer, then Sagrada Familia ought to be accepted. And Ayers Rock for those of us who can never remember Uluru. I thought I had spelled Kathmandu correctly--can you check?
Suggest accepting Schoenbrunn or Schonbrunn...I never would have thought to start it with "Palace." Fun quiz, but I missed a lot of them because of similar semantic reasons--even ones that I have visited!
Good idea, I will circle back and add more variants. I know it helps me on other quizzes, so I'd like to do the same for mine. Glad you enjoyed it. All the best.
