An ancient site of human settlement, the history of Elven can be traced back to the
Bronze Age with archaeological evidence discovered in the commune, in particular the village of Bocolo where the cache of a metal smelter was found. There are also many
megaliths in the canton: these include the Loge-Aux-Loups on the road to Trédion, the Pierre Tabulaire de la Bataille in the Coeby forest and the twin
menhirs of Babouin et Babouine that were carved with faces at an unknown period. The commune of Elven was founded by religious leaders who emigrated across
the Channel from
Britain in the fifth century. The name evidently comes from Saint
Elwen or Elven. A castle was built around AD 900 to defend against the
Norman invasion. The present castle Largoët was built in the fourteenth century from the town in the middle of a great expanse of woods and was the seat of the Marshall of Brittany.
Henry Tudor Duke of Richmond, the future Henry VII of England, held it between 1474 and 1476. He stayed at most of the ducal and seigneurial houses in Brittany but stayed here the longest. The castle differed little from English castles but its striking feature was a 144-foot donjon of six storeys completed in 1475, isolated from the rest of the castle, by a moat. It was on the sixth floor of this Tour d'Elven that Henry, Duke of Richmond spent two years. Elven was part of the
Chouannerie, a royalist uprising at the end of the eighteenth century. Indeed, the head Chouan Joseph Gambert, captain of the canton's companies, was killed near the village of Panistrel in 1794. A street now bears his name. Underground chambers inhabited by the Chouans can be found in the Saint-Bily woods. The 1988 film
Chouans! was partially made on location in Elven. During the
German occupation, Elven was the scene of the first airborne operation, dubbed
Operation Savannah, on 15 March 1941. A monument commemorates the event on the road to
Questembert. Three members of the
French Resistance were shot in July 1944. The Rue des Martyrs de la Résistance is dedicated to them. ==Heraldry==
