Located west of Saint-Laurent, near the “route de Lons-le-Saunier”, the chapel draws the eye due to its windmill shape - only its vanes are missing. It appears that this structure was once a mill for the hamlet of Voisinal de Joux. Its tapered roof, mounted on wheels is set atop its eight-metre high tower. Its vanes were broken during a hurricane in 1829. Another chapel was built on top of its remains as early as 1850. Although in bad condition since a fire in 1907, it bears the French flag that marks the border set during the second world war. Today, it is home to Marie-Thérèse, a bell cast in 1953 by the Paccard bell foundry in Annecy.
