The Queen will be laid to rest inside St George's Chapel at Windsor Castle
The tiny chapel houses the remains of the late Queen’s father, King George VI, the Queen Mother and Princess Margaret.
When the Duke of Edinburgh died in April 2021, his coffin was placed in the 200-year-old Royal Vault beneath St George’s Chapel
However, this is not Prince Philip’s final resting place, and he will be transferred to the memorial chapel within St George’s to lie alongside his wife’s coffin.
The memorial chapel was built in 1969 after the death of King George VI. The King was originally interred in the Royal Vault when he died in 1952, before being moved to the memorial chapel upon its completion.
It will hold the remains of Queen Elizabeth and her husband Prince Philip, and already houses the bodies of George VI, the Queen Mother and Princess Margaret.
The pale stone annexe has a black stone slab set into the floor and is located on the north side of St George’s behind the North Quire Aisle.
The third and final service - a private untelevised interment in the King George VI Memorial Chapel - will begin at 7.30pm.
The service, also conducted by the Dean of Windsor, is open only to the King and Royal Family.
They will lay the Queen's coffin to rest in the George VI memorial chapel alongside her deceased relatives.
She will join her parents King George VI and the Queen Mother, Princess Margaret and her husband, Prince Philip.
