Louis was baptised at the royal chapel at St James’s Palace – the same venue as George’s service. The Tudor-style building has been home to generations of royals, way back to the time of the notorious King Henry VIII.
While it’s no longer the official royal seat, the palace houses several official offices, societies and collections.
It’s a landmark steeped in history and Queen Victoria posed with her new husband, Prince Albert, on the palace steps in 1840.
The chapel has special significance for Louis’ parents. It’s where Kate was confirmed by the Church of England before her wedding in 2011.
It’s also where Princess Diana’s body was kept after her death in 1997. Her loved ones took their leave of her there before her public funeral at Westminster Abbey.
