Chris Slade describes the son et lumiere presentation at the abbey of Bon Repos called "Le Pays de Conomor" in Brittany, which takes place during the first two weeks of August.
You would not not have heard any bells in France over the Easter weekend, not even the midday bells have been heard.
Tradition goes that all the bells have gone to Rome and they return on Easter Sunday. As they fly over the gardens on their way back to their rightful bell towers they drop Easter eggs and chocolate rabbits and chickens in all the gardens across France, ringing as they leave.
This is the signal for all the children to dash outside and to search for the hidden chocolate goodies.
