Municipality of Ille-et-Vilaine, in Brittany, Châteaubourg takes place at about twenty kilometers from Rennes. The one who merged with Broons-sur-Vilaine and Saint-Melaine in 2014, is located near vitreous, champeaux and cornillé.
The former Castelburg is cited in the registers from the eleventh century, attested by the existence of a seigneury and a Benedictine priory on its territory. The municipality develops over the centuries, suffering from the war of succession of Brittany in the 16th century or wars of religion in the sixteenth.
Today very active from an economic point of view, the Breton city attracts a large number of visitors because of its proximity to some of the most beautiful cities in the region and its exceptional heritage.
