Description

Exchanges will be made between the three Chappe de Haute Maurienne telegraphs: the Plan de l'Ours (Saint André), Courberon (Avrieux) and the Mollard-Fleury (Val Cenis-Sardières).
Built in 1806 at the request of Napoleon I, they were part of the 33 stations on the telegraph line connecting Lyon to Turin.
