Le Fâ
Barzan, France
The temple of the Moulin du Fâ is an ancient fanum, a Celto-Roman temple located in the commune of Barzan in the Charente-Maritime department of France. Possibly dedicated to Mars, it is part of the relatively uncommon group of circular-plan temples in Roman Gaul. In the first half of the 2nd century, it replaced one or possibly two earlier sanctuaries. Its cella, with a diameter of 21 meters, stands at the center of a circular podium 36 meters in diameter, and the overall structure may have reached a height of approximately 40 meters. The remains survive at ground level, similar to other buildings of the secondary settlement—possibly identified as Novioregum—of which it was a part. The ruins were listed as historical monuments in 1937 or 1939.
