Merville-Franceville-Plage lies where the Orne meets the Channel, on the eastern side of the estuary opposite Ouistreham, 6 km from Cabourg and 14 km from Caen. The parish of Merville is medieval: it appears as Matervilla in 1078 in the cartulary of the Trinité de Caen, the abbey founded by William the Conqueror’s queen Matilda, and its church of Saint-Germain keeps 12th-century work under a 19th-century rebuilding. A medieval manor stood here until it was destroyed around 1467–1468. Across the bay at Dives-sur-Mer, William assembled the invasion fleet of 1066, which is the most famous medieval fact of this coast.
The seaside half of the name is much younger: the resort of Franceville was laid out in 1898 by the architect Joseph Édouard Wattier on the dunes east of the village, and the two were joined as Merville-Franceville-Plage. On 6 June 1944 the Merville Battery, a German gun position covering Sword Beach, was stormed by about 150 lightly armed paratroopers of the 9th Parachute Battalion under Lieutenant-Colonel Terence Otway; the casemates are now a museum. The commune has about 2,200 permanent inhabitants and many more in summer.
Since 2006 the village has become Merravilla for one weekend each September, when the Association Raid Tolkien and the town hall stage Cidre & Dragon, a free medieval-fantasy festival that draws more than 70,000 people. Caen is the nearest city and station, with coastal buses to the village.
