Baptistere Saint-Jean, Poitiers

Supposedly the oldest existing Christian building in the West and a spectacular example of Merovingian architecture. Interesting part of the history of this building was that it was abandoned around late 1700 during the "Revolution", confiscated from the church, sold to a private citizen who used it as a warehouse! Repurchased and saved from demolition, underwent restoration in the mid 20th century. Worth exploring.

There is a small charge, which seems flexible if like us, you have a large family. Worth it to see what is claimed to be the oldest christian building in France. There is a leaflet that explains everything. Well worth the walk from the centre of town if you are interested in history.
