Water Body
Lake Guerlédan is an artificial lake in the centre of Brittany, France. It extends across the borders of the departments of Morbihan and Côtes-d'Armor, within the communes of Saint-Aignan, Morbihan and Mûr-de-Bretagne. At an elevation of 121 m, its surface area is 4 km². Lake Guerlédan is the largest artificial lake in Brittany.This Lake was created to power the dam of Guerlédan. Construction took seven years from 1923 to 1930, and encountered many geological, technical and financial difficulties. The creation of the lake and especially that of the dam cut the through the Nantes-Brest canal which from this location, followed the course of the river Blavet. Seventeen of the old locks on the canal were submerged in the Lake. Lake Guerlédan is now a tourist attraction, offering various watersports, walks and panoramic views.During World War II, the Breton nationalist architect James Bouillé advocated a radical plan to build a new Breton capital city on the shores of Lake Guerlédan, to be called "Brittia". Bouillé believed this could be a "Celtic Brasilia".Beginning in 1951, the Lake was regularly drained for repair, the last time being in 1985, revealing a hidden landscape of submerged locks and buildings. Modern technology will reduce this frequency but now the lake has been temporarily drained for the last time in a generation new maintenance access is being installed so that the dam's hydro-electric system can be checked without the need to drain.

  • Parties with our three children aged 10, 8 and 5 in touring for two hours along the Lake Guerlédan. We were initially surprised by the absence of tourists on this magical place while the weather was great and during the Thanksgiving holiday. We had a bit of trouble to locate the start of the hike then after 30 minutes we found the basis for long and the Lake and lead at the top of the dam. Too bad that you can not walk on the dam but see the broadside of the Lake Forest, it's fabulous! And then we decided to go down the Valley to admire the dam "from below": impressive building! We could we walk along the water course, taste, then back quietly. Each spot observation is incredible, almost black and placid lake is mesmerizing. A highlight of our holiday in Brittany!
