I missed 4 things because I couldn't word them right. Mont St Michel, Terracotta army, parthenon in Athens (acropolis) and Manhattan (New York skyline). Also guessed "Hong Kong", but didn't know how to specify it and there were a couple of more similar ones.
You should accept "Pisa" for leaning tower of pisa, "Kathmandu" for Kathmandu valley, and give more clues for Sahara desert like "Egypt, Morocco, Algeria, Libya" for example.
