Prince George is yet to be seen together with both his younger siblings, with the youngest Prince missing recent events including his uncle Prince Harry's wedding and the Queen's Birthday Parade, Trooping the Colour. The date fits in perfectly with Prince Harry and Meghan's busy schedule as it falls one day before their official two-day visit to Dublin.
The Chapel Royal is the same venue used for Prince George's christening on 23 October 2013.
Following in the tradition of all the other royal children - including his older brother Prince George and Princess Charlotte - Prince Louis will be welcomed into the Church of England at the ceremony, presided over by the Archbishop of Canterbury at the Chapel Royal at St. James's Palace in London.More news: Trump threatens another $200 billion tariffs on China
