Prince Charles and Camilla Parker Bowles have had their wedding blessed at St George's Chapel in Windsor.
Around 800 family and friends attended the service of prayer, including the Queen and Prince Philip.
Earlier the couple married at a private service at Windsor Guildhall in front of 30 close friends and relatives.
Thousands of people packed the streets of Windsor to catch a glimpse of the royal couple as they left the registry office after the 20-minute service.
Camilla is now the wife of the future king, and has the new title HRH Duchess of Cornwall.
She wore an oyster coloured outfit and hat at the first ceremony, changed into a blue silk dress for the blessing of her marriage.
During the service, the couple promised to be faithful to each other for the rest of their lives.
Guests included members of the royal family, politicians and some of the couple's celebrity friends.
After the ceremony, the couple walked around and chatted to members of the public waiting outside the chapel.
Guests then went to the reception at the palace, where they were reportedly served food including smoked salmon and egg cress sandwiches.
Mini Cornish pasties, mini vegetarian pasties and ice cream cornets were also part of the wedding feast.
A huge security operation was mounted to protect the important guests, and hundreds of police officers patrolled the area.
The castle is said to have been decorated with thousands of flowers, including lots of yellow spring daffodils, pink and cream lilies, camellias, hydrangeas, roses and blossom.
At both the civil ceremony and the blessing Prince William and Prince Harry arrived on a 'royal coach', along with loads of other family members including aunts, uncles and cousins.
The civil ceremony took place at 12.30pm at the Guildhall.
Crowds cheered as the royal party drove by, adding to the party feeling with people wearing hats and waving flags.
Many royal fans braved the cold, camping outside the venues overnight to secure a good view of the happy couple.
Lizzy, 9, from Maidenhead told CBBC Newsround: "It's an historic occasion - I'm very happy to see Charles and Camilla get married!"
