The 80th anniversary commemorations of the Normandy Landing attracted record crowds, with over 350,000 people turning up on 6 June, local authorities reported.
More than 2.5 million domestic and foreign tourists visited Normandy from 1-9 June, they said.
During the nine-day period, Normandy hosted an average of 300,000 daily visitors, about 60% of them from abroad.
The success of the Normandy Landing in 1944 marked a pivotal turn in the Second World War, hastening the fall of the Nazi regime.
Paris was liberated in August 1944 and Allied forces reached the German border in September of the same year.
