...would not be my first port of call if I were on holiday in Paris, to be honest. It’s very crowded and for me, there are more impressive churches (Sainte Chapelle) and better things to do. Although to be fair, I had the time to visit other cathedrals in France – if Notre Dame had been the only one I visited, maybe I’d be more impressed.
I definitely would not advise going to mass here, as they still let people in during the mass and it’s very disconcerting trying to remember the prayers when there are tourists talking loudly and taking pictures around you. I would like to visit during Holy Week though, as it’s the only time of the year when the collection of relics is displayed.
