We visited here on Tuesday 5 July. A very stunning church which was started in the 8th century. It is at the mouth of the river Couesnon, in Normandy (not Brittany!). It is linked to the mainland by a causeway – which I am happy to report is going to be removed in 2012 🙂 It is one of hte most beautiful buildings in France I have seen. While we were there (with the other 1000’s of tourists), we had a fantastic guide who was French but had very good humour – which made it entertaining for us (ask me about the bus that got caught in the tide).
