President Joe Biden and his aviator sunglasses met Queen Elizabeth II on a bright Sunday afternoon.

The queen hosted the president and first lady Jill Biden at Windsor Castle, her royal residence near London. Biden flew to London after wrapping up his participation in a three-day summit of leaders of the world’s wealthy democracies in Cornwall, in southwestern England. He arrived at the castle aboard the presidential helicopter and was ferried to the queen in a black Range Rover.

The 95-year-old monarch greeted the Bidens in the castle’s quadrangle, where she waited beneath a covered dais that shielded her from the sun on one of the hottest days of the year so far in the United Kingdom. Assembled soldiers from the Queen’s Company First Battalion Grenadier Guards gave a royal salute and the Bidens placed their hands over their hearts as the US national anthem was played.
