Pelton Grange Care Home resident Dennis Fullerton and his wife Margaret were surprised by staff when they returned from an anniversary lunch to banners and flowers.
Staff also presented Margaret with a bouquet and Dennis with a bottle of whisky – before offering the happy couple glasses of bubbly to toast their 50 years together.
The pair married in September 1968 at Byermoor, near Stanley, County Durham, spending their wedding night in London and honeymoon in Austria.
Dennis was a uniform inspector for the Northumbria Police, before retiring and eventually moving into Pelton Grange Care Home in March 2017.
Home manager Chris Hogan-Hind said: “50 years of marriage is an amazing milestone, so we decided to throw a little surprise to mark the special occasion.
“Dennis and Margaret are such a lovely couple and we were delighted to see them toast their special day with a glass of bubbly.”
