La Pierre de Champ Martin
La roche-chalais
The Champ Martin stone marked the boundary between the seigneuries of Saint-Aulaye, Montpon and Fronsac. This rectangular stone was 5 to 6 feet high, and was made of “pierre de grison”, a local Double stone.
The 15th-century stone was removed and a stele was installed there and inaugurated in September 2022.
