Kate Middleton Visits World War II Center at Bletchley Park: Photos

For her most recent royal outing, Kate Middleton looked pretty in polka dots as she paid a visit to Bletchley Park, a secret wartime spy base, on Tuesday, May 14. There, the Duchess of Cambridge viewed “a special D-Day exhibition in the newly restored Teleprinter Building, marking the 75th anniversary of the D-Day landings,” Kensington Palace confirmed on Twitter.

The World War II code-breaking center holds special meaning for the 37-year-old, considering her paternal grandmother, Valerie Glassborow, and her twin sister, Mary Glassborow, worked at that exact center throughout the war. Following her first visit to the spy base nearly five years ago, Kate opened up about discovering more about her grandma.

“I have always been immensely proud of my grandmother, Valerie Glassborow, who worked at Bletchley Park during the Second World War,” she admitted in 2016 for a special puzzle book produced by GCHQ, the U.K.’s Signals Intelligence and Cyber Security agency. “She and her twin sister, Mary, served with thousands of other young women as part of the great Allied effort to break enemy codes. They hardly ever talked about their wartime service, but we now know just how important the men and women of Bletchley Park were, as they tackled some of the hardest problems facing the country.”

During this visit, Kate smiled ear to ear as she met with schoolchildren and fans to prepare for the upcoming 75th anniversary of D-Day. Scroll down below to learn more about Kate’s busy day at Bletchley Park!
