This location was one of two sites chosen to establish the necessary port facilities to unload quantities of supplies and troops needed for the invasion during June 1944, the other was built further West at Omaha Beach. The British built huge floating concrete caissons which, after being towed from England, then had to be assembled to form walls and piers forming and defining the artificial port called the Mulberry harbour. These comprised pontoons linked to the land by floating roadways. One of these ports was assembled at Arromanches and even today sections of the Mulberry harbour still remain with huge concrete blocks sitting on the sand and more can be seen further out at sea.
