The three-day long celebrations to officially mark the 90th birthday of Queen Elizabeth II and the Duke of Edinburg, who turned 95 on Friday, began with the release of a photograph to commemorate the joint birthday of the royal couple. Here are the 10 best moments from the royal celebrations.

The Queen and Prince Phillip attended a special thanksgiving ceremony at a star-studded St. Pauls Cathedral in London. The ceremony was attended by the Duke and Duchess of Cambridge, Prince Harry and other members of the family. High profile politicians, celebrities, and other dignitaries were also present at the ceremony that marked the beginning of the celebrations.

Looking glorious in yellow, the Queen arrived alongside Prince Phillip and waved at her fans.

The Archbishop of Canterbury, Justin Welby, delivered a touching speech on the Queen’s dedication and service to the country to a gathering of more than 2,000 people at the St. Paul’s Cathedral.

“Your Majesty, today we rejoice for the way in which God’s loving care has fearfully and wonderfully sustained you – as well as Prince Philip marking his 95th birthday today,” the Mail Online quoted Archbishop Welby as saying.

British Prime Minister David Cameron and broadcaster David Attenborough also addressed the crowd at the service, praising Her Majesty’s long rule, the CNN reported.

Grenada High Commissioner Karl Hood said that Prince Harry told her that the best birthday present for the Queen would be a day off when she can just “lie about and do nothing.”

Prince Edward’s wife Sophie and his children, James and Louise, the Prince and Princess Michael of Kent, Countess of Wessex and Princesses Beatrice and Eugene also attended the ceremony, the Mail Online reported.

Besides Cameron, the most notable politicians present at the ceremony were George Osborne and Jeremy Corbyn.

The spectacular events planned over the weekend include Trooping the Colour ceremony on Saturday and a parade down The Mall on Sunday.

The British Royal family will make an annual appearance on the Buckingham Palace balcony on Saturday which will end with a flypast by the British Royal Air Force.

On Sunday, the Queen will host a street party, the Patron’s Lunch, on The Mall for 1,000 people. The event will celebrate the Queen’s patronage of over 600 charities and organisations on the occasion of her birthday.
