Among the heritage riches of Pontivy Community, industrial history shapes the landscape of the territory and tells us more about its know-how and its economic past.

Canals

The pipeline of Blavet and Canal from Nantes to Brest, first launched on the initiative of Napoleon Ier for military purposes, ultimately constituted a flourishing river artery for trade from the mid-19e century. During a walk along the towpath, it is easy to imagine the incessant parade of barges, the lockages during which bargemen and lockkeepers rubbed shoulders for a few moments or even the fishermen and washerwomen who occupied the banks of this course water that punctuated their daily lives.

The windmills

The remains of mills and flour mills remind us of the importance of water as a driving force. Grain mills and tan mills have contributed to the economic wealth of the region since the Middle Ages. Water, as well as iron ore and the abundance of wood from the Quénécan forest, fueled for centuries the forges of the steel village of Les Salles, near the Guerledan Lake.

The Guerlédan lake dam

The construction of Guerlédan hydroelectric dam, in the 1920s, constituted a real technical feat for the time and was the promise of a more comfortable life thanks to the progressive electrification of the countryside. The dam also, however, definitively puts an end to commercial navigation on the canal, along which the railway lines take over and make it possible to remarkably develop the transport of people and goods. Since 2021, the rails have once again welcomed passengers curious to discover the Blavet valley aboard the tourist train Napoleon Express.
