Queen Elizabeth II is on an official visit to France to commemorate the 70th anniversary of D-Day. In a very busy day of engagements, the queen, accompanied by the Duke of Edinburgh, first visited St. Pancras Station in London on June 5, 2014 where she unveiled a plaque marking the 20th anniversary of the Eurotunnel’s opening. The couple boarded a Eurostar train and traveled to Paris where they arrived at the Gare du Nord station. The queen was then welcomed by French President Francois Hollande at the Elysee Palace. The president and the queen paid a visit to the Arc de Triomphe where they laid a wreath at the Tomb of the Unknown Soldier. The day culminated with an official reception held at the British Embassy in Paris. The packed day of engagements proved to be an impressive display of stamina for the 88-year-old monarch and her soon-to-be 93-year-old husband. Photos by Getty Images.
