King Charles III will be buried in the King George VI Memorial Chapel at St. George’s Chapel, Windsor Castle.
This is the planned location for several reasons:
Important Context: The specific details and date of his burial will not be confirmed until after his death. The funeral and burial will follow a meticulously pre-planned operation (code-named “Operation Menai Bridge”), which will include a period of lying-in-state, a state funeral at Westminster Abbey, and a committal service at St. George’s Chapel before the private burial in the memorial chapel.
In summary, while the full state ceremony will be a major national event, the final, private resting place for King Charles III is planned to be alongside his parents in the King George VI Memorial Chapel at Windsor.
