The landscape centred on the church of Rennes-les-Bains is divided into twelve segments by six alignments.
Two of these are the original Roman cardo-decumanus axes of the village. Another is the 45° alignment. The red path marks the pathway of a circumambulation in the landscape around Rennes-les-Bains. This division of territory into twelve segments around a sacred centre was a practise widely adopted in the ancient world, and described by Plato.
