Seaside resort of Normandy, Lion-sur-Mer takes place in the department of Calvados, on the Coast of Nacre and the shores of the Channel Sea. The town is about fifteen kilometers from Caen, not far from Douvres-la-Délivrande and Ouistreham.
The site of the municipality is occupied since Antiquity, as evidenced by certain vestiges of buildings dating after the colonization by the Romans. However, it was not until the Middle Ages that the village of Lion-sur-Mer really formed, becoming a small fishing port as early as the 12th century. The city was transformed into a seaside resort in the 19th century, with the fashion of sea bathing. Villas were quickly built on the water's edge, and Lion-sur-Mer now turned mainly to tourism.
Place of disembarkation of British troops on 6 June 1944, the city labeled Commune tourist, is also known for its role in the Second World War.
