 SANDRINGHAM, England (AP) — A heavy cold is keeping Queen Elizabeth II from attending the traditional Christmas morning church service near her Sandringham estate in rural Norfolk, England. 
 
 It is extremely rare for Elizabeth to miss the service, which is a cornerstone of the royal family's Christmas celebrations and brings the monarch into contact with local residents who gather outside for a glimpse of her. 
 
 "The Queen continues to recover from a heavy cold and will stay indoors to assist with her recovery," Buckingham Palace said. "Her Majesty will participate in the royal family Christmas celebrations during the day." 
 
 Those festivities usually include a gala lunch. In past years, the royal family would often go for extended walks in the countryside. 
 
 Elizabeth has been in generally good health and has maintained an active schedule in the last year despite traveling less often than in the past. 
 
 Her husband, 95-year-old Prince Philip, has also cut back his public schedule and his charitable works. He was also suffering from a heavy cold earlier in the week, the palace said. 
 
 The flu season has hit many Britons hard in the last two weeks and colds and flus are spreading. A cold can be dangerous for people in their 90s, doctors warn. 
 
 Earlier this week, the royal couple delayed their departure from London to Sandringham because of their colds but traveled one day later than expected, using a helicopter instead of a train. 
 
 The royal family received some sad news Saturday, when it was revealed that the queen's granddaughter, Zara Tindall, had suffered a miscarriage while expecting her second child with husband Mike Tindall. 
 
 The queen plans to use her pre-recorded Christmas Day message to praise British Olympic and Paralympic athletes and others who inspired her. 
 
 The message will be televised throughout Britain and much of the Commonwealth on Sunday afternoon. 
 
 Remarks released by Buckingham Palace indicate she will say she often draws strength from meeting ordinary people doing extraordinary things. 
 
 Elizabeth and Philip will be joined in Sandringham by other senior royals. Prince William and his wife Kate, along with their two children, Prince George and Princess Charlotte, are celebrating Christmas with Kate's parents.
– Britain's Prince Philip remained hospitalized today, recovering from coronary stenting, but the royal show must go on, and so it did: Queen Elizabeth and her entire brood attracted throngs of Brits as they attended Christmas services this morning at the queen's retreat in Sandringham. Kate, in her first Christmas as Duchess of Cambridge, likely boosted the number of watchers, notes People, and impressed in an eggplant-colored coat and hat. The royals were also joined by Mike Tindall, who married the queen's granddaughter, Zara Phillips, this year. The matriarch herself stressed the importance of family in a pre-recorded Christmas address, notes the AP, though she said that family might "not necessarily mean blood relatives, but often a description of a community." Members of the family were to visit Philip later today. Click through the gallery above for more scenes.
