With around 160,000 Allied troops crossing the Channel on D-Day alone, the Normandy landings represented the largest seaborne invasion in history.
They faced a German army which had spent years building an Atlantic Wall of defences against invasion, and an estimated 4,400 Allied soldiers - mostly British, American and Canadian - never made it home.
The events of June 6 1944, known as Operation of Overlord, were one of the key battles of the Second World War, which started in Europe in September 1939 and ended in May 1945.
Last year, the 75th anniversary of the landings, saw a range of events to commemorate the landings, although plans for this year have largely been scrapped due to the coronavirus pandemic.
