Congratulations are in order for Prince William and Princess Catherine.

The royals marked their 13th anniversary today, April 29, by sharing a photo from their wedding. In the black-and-white image, William is seen standing behind Kate, holding her waist as she holds her white flower bouquet with both hands. They both smile widely—Kate in her stunning ivory lace Sarah Burton dress, tiara, and veil, and William in his military uniform.

The Prince and Princess of Wales shared the image on their social media channels. “13 years ago today!” they wrote in the caption. A Kensington Palace spokesperson confirmed the photo, taken by Millie Pilkington, had not been previously released.

William and Kate began dating after they met as students at the University of St. Andrews in Scotland in 2001. They wed a decade later, on April 29, 2011, in a grand royal ceremony held at Westminster Abbey in London. They have since welcomed three children: Prince George, 10, Princess Charlotte, 8, and Prince Louis, 6.

Last month, Princess Kate revealed to the world that she’d been diagnosed with cancer and is receiving preventative chemotherapy. In a personal video message to share the announcement, she also praised her husband for always being by her side and helping her through her recovery. “Having William by my side is a great source of comfort and reassurance, too,” she said. “As is the love, support, and kindness that has been shown by so many of you. It means so much to us both.”
