Wearing a turquoise coat and matching hat, Queen Elizabeth II arrived at St. Mary Magdelene Church on her sprawling Sandringham estate in Norfolk. She was accompanied in a Bentley by granddaughters Beatrice and Eugenie.
Her husband, Prince Philip, walked from the house to the church with other members of the royal family.
Three familiar faces were missing from the family outing. Prince William is spending the holiday with his pregnant wife Kate and his in-laws in the southern England village of Bucklebury. Prince Harry is serving with British troops in Afghanistan.
Later Tuesday, the queen will deliver her traditional, pre-recorded Christmas message, which for the first time will be broadcast in 3D.
