Inhabitants are called Colombanais in French.
Its name comes from Saint Colomban, who came in the years 580 - 590. Accompagnied by several monks, he crossed the English Channel and arrived either on the Du Guesclin beach, either a few hundreds meters further in the west.
This commune has several beaches, very frequented by tourists in summer.
The Malouinières are historic buildings built between 1650 and 1730 within 12 km (7.5 mi) of Saint Malo, by its shipbuilders who wanted to escape the congested city, while staying close enough to the centre (within two hours on horseback) to take care of their ships and their cargos.
