1-year-old Prince Louis makes royal balcony debut

Prince Louis was the kid of the hour at Saturday’s Trooping the Colour festivities in London, where Prince William and Kate Middleton‘s youngest son made his debut on the Buckingham Palace balcony, alongside older siblings Prince George, 5, and Princess Charlotte, 4.

The young royal, who turned 1 in April, also posed alongside Queen Elizabeth II, Prince Charles and Camilla Parker Bowles, and his aunt and uncle, Prince Harry and Meghan Markle. Saturday marked Meghan’s first public appearance since introducing son Archie Harrison Mountbatten-Windsor to the world last month.

Trooping the Colour, which officially marks the birthday of the Queen, who turned 93 on April 21, is a parade that “moves from Buckingham Palace and down The Mall to Horse Guard’s Parade, alongside members of the royal family on horseback and in carriages,” as described on the royal family’s website. The festivities conclude with a fly-past from the Royal Air Force, which can be seen from the palace balcony.
