To commemorate the centenary of the start of hostilities of the First World War, members of the British and Belgian royal families met in Liege, Belgium on August 4, 2014. The first battle of the conflict took place in Liege, which endured heavy shelling, earning the city the Légion d’Honneur, France’s highest honor. King Philippe and Queen Mathilde of the Belgians presided over the commemorative ceremonies, accompanied by the Duke and Duchess of Cambridge, and King Felipe VI of Spain, as well as other dignitaries. After a luncheon was held at Liege’s town hall, the royals were joined by Prime Minister David Cameron and Prince Harry as well as German President Joachim Gauck at St. Symphorien, a cemetery for British and German soldiers who were killed at the Battle of Mons, where more commemorations were held.
