Mers-les-Bains is a commune in the Sommedepartment in Hauts-de-France in northern France. Much of the older part of town developed in the heyday of seaside bathing, during the latter part of the 19th century. As a consequence, the fine villas that were developed in those times are now subject to preservation orders. Any refurbishment must be in the same materials and colours as the original work. No plastic doors or roller shutters are allowed. read more…
