The bell tower of the church of Saint-Pierre in Tonnerre. Can you see the pigeon under the right-hand arch?
While it's easy to walk up to the church from the streets of town, cars are sent high up above the church before they can wind their way back down to it. We had the car and the dog, so we drove. Unfortunately, the church was locked up tight and we didn't get to see inside. But we had a nice walk around the outside and took in the views over the town's rooftops.
One of the church's stained glass windows, seen from the outside. The sunlight was shining through the building from the other side.
