The caption read: "Happy one year anniversary to Their Royal Highnesses, The Duke and Duchess of Sussex! Today marks the one year anniversary of the wedding of The Duke and Duchess of Sussex. Their Royal Highnesses exchanged vows at St George’s Chapel within the grounds of Windsor Castle on May 19th, 2018. The selected song “This Little Light of Mine” was chosen by the couple for their recessional. We hope you enjoy reliving this moment, and seeing some behind the scenes photos from this special day."
