In pictures: The Queen at Sandringham, the Norfolk retreat that became her home from home
Throughout her life, Sandringham was the Queen's royal retreat - a holiday hideaway where she escaped the spotlight.
Sandringham House in Norfolk was a place where she spent childhood years, watched her own children grow up, and spent many a Christmas Day lunch with her family.
But she also became a part of the community - attending church services for Christmas Day, Easter, christenings and more, and attending meetings of the Women's Institute whenever she visited.
The estate holds an established place in royal history, being where the previous two monarchs died, and the location from which the Queen made her first Christmas Day speech to the nation.
