Staff at Simonsfield Care Home, on Boston Avenue, dressed as land girls for the occasion and residents donned Union Jack headscarves.
The home was also decorated in Union Jacks, while everyone enjoyed food, drinks and a sing along.
They were treated to entertainment from singer Sharon Wallace, who made headlines earlier this year after creating knitted sleeves to stop those with dementia potentially harming themselves by removing their cannulas.
Debbie Smith, home manager at Simonsfield Care Home, said: “Despite most residents being too young to be involved in the forces at the time, many recalled memories from when they were younger about the D-Day landings and the War.
“Commemorating D-Day and the Second World War can be a somber occasion, as many recall losing family and friends but, having discussed the upcoming anniversary with residents, they wanted to celebrate and remember those who fought in the War.
“Everyone had a fabulous time at the street party and said it was a fitting tribute to those who sacrificed so much.”
Resident Marg Jones added: “I remember how brave the land girls were. What a lovely tribute to them with everyone making a real effort.”
