Grandcamp-Maisy. Grandcamp-Maisy is a commune in the Calvados department in the Normandy region in northwestern France.
Grandcamp-Maisy is located on the coast, 9 kilometres north east of Isigny-sur-Mer and 4 kilometres west of Pointe du Hoc. It is an active fishing port, with a fish market located on the harbour side.
On 1 November 1972, the commune formerly known as Grandcamp-les-Bains amalgamated with Maisy and changed its name to Grandcamp-Maisy. In 1944 the town of Maisy was the site of a German heavy artillery battery and the headquarters for the sector.
Until early in the 21st century, the site was overgrown and had been covered by US engineers before the end of 1944-well before any historians had a chance to examine the site. British military historian Gary Sterne rediscovered the site after finding an American invasion map, and purchased the site and turned it into a museum with over 2 miles of original German trenches and bunkers.
From his research and released papers, the site is many times larger than was originally thought. The labyrinth of trenches and tunnels had remained hidden for around 60 years. It contains office bunkers, supplies buildings, general quarters, radio rooms, and many other blocks, including an underground hospital. It may well be that when all the site is cleared and all the bunkers that are buried are rediscovered, this site will be one of the largest
