Personally I reckon Palace of Versailles is one of the must-visit for first timers in Paris, together with the Louvre, Arc de triomphe and the Eiffel Tower. Everyone seems to put Notre Dame on the must-see list, however I really don’t think it is that spectacular, there are a lot of other amazing churches in Europe. York was one of those tourists last year, he did not leave the Paris city center and had not heard of Versailles before (shock horror!). I have visited Versailles when I was a kid, I really wanted to show York why this place is so popular!
