Julien Harté
November 15, 2025, Le Moulin de Guipry-Messac

This former watermill, documented as early as 1089, was initially used as a fulling mill before being converted into a flour mill in the 19th century. Its operation ceased on December 31, 1974. Since then, the building has stood as a significant heritage landmark, marking the industrial and riverine history of the Vilaine Valley.

Hello everyone, The bridge has been dismantled for two years, undergoing repairs in the navigation workshops. I hope to see it again one day.

The castle is a self-guided tour. A little tip: there are bike racks inside the castle, just beyond the entrance.
