St John Baptistry
St John Baptistry information
One of Poitier's most celebrated gems is this baptistry, built in the 4th century on Roman foundations - making it (reputedly) the oldest Christian building in France. It was redecorated in the 10th century and used as a parish church. The octagonal hole under the impressive frescoes was used for total-immersion baptisms, practised until the 7th century.
