The archaeology was fascinating and well worth the visit. There was an issue with retrieving the tickets from Headout online - it depends on having a smart phone that is functioning properly and mine took over 24hrs to sort itself out having arrived in France. I could not get my Headout tickets to show - I had to show my receipt instead, and they kindly let us in.

We had been to Paris several times before but this was really a winner. We went mainly for Notre Dame. Well we thoroughly enjoyed that. The crypt was a highlight so cleverly exposed. Also the new cathedral was very nice weather to see the cathedral in its full glory. We enjoyed
