History
It is best known to English historians as being the ancestral seat of Ralph de Guader the first earl of Norfolk and Suffolk in post-Conquest England circa 1070 A.D. This is an ancient Breton parish to the west of Rennes, whose boundaries formerly stretched to include the territories of Bran, Muel, Saint-Onen, Crouais, Saint-Méen-le-Grand, Concoret and Loscouët-sur-Meu. The parish of Gaël was a dependency of the Archbishopric of Saint-Malo. In the 6th and 7th centuries, Gaël was a major town in the kingdom of Domnonia. The name is alleged to derive from the word for a ford, river-crossing or river. In local myths there was a 6th-century king Hoël known as the forest king or "Rex Arboretanus". It is a fact that the town is situated amidst the vast forests of Poutrecouët. A royal castle from this era was sited at Meu, not far from Gaël. This later became the seat of the De Montfort family. The emplacement was captured and dismantled by De Guesclin in 1372. During World War II, the German Luftwaffe occupied an airfield near Gaël in 1941. The Allied Air Forces based in England attacked the airfield on several occasions in 1943 and 1944 before it was seized by the United States Army in June 1944. Known as Advanced Landing Ground "A-31", the 354th Fighter Group based P-51 Mustang fighters at the airfield from 13 August through 17 September 1944 before moving east to Orconte in the Marne département along with the advancing Allied armies. After the war, the airfield was dismantled and the land returned to agricultural use.
