The towers | ©Vi..Cult... / CC-BY-SANo, it's not a fortress, but really the church of Saint-Laurent, raised in the 12th century! OK, OK... the square keep, the only vestige of the old castle raised at the same time, links the church and seems to make one and only building! Jacques Duèze, especially, fortified the castle in the 14th century, when this one belonged to bishops of Avignon.
