Marking her 60-year reign
Queen Elizabeth II waves to spectators on June 3 with Prince Philip, Duke of Edinburgh; Camilla, Duchess of Cornwall; and Catherine, Duchess of Cambridge, while cruising along the River Thames in the Spirit of Chartwell during the Diamond Jubilee River Pageant in London.

Thousands of well-wishers descended upon London this weekend to celebrate the 60th anniversary of the Queen's ascension to the throne. In addition to the elaborate river parade, other Jubilee festivities included a star-studded free concert at Buckingham Palace, a carriage procession and a service of thanksgiving at St Paul's Cathedral.

In one of the most striking displays of the Diamond Jubilee weekend, a flotilla of nearly a thousand rowing boats accompany the Spirit of Chartwell as it makes its way down the River Thames.

With the exception of Queen Victoria in 1897, Queen Elizebeth II, who was coronated in 1953, is the only monarch in the commonwealth's history to have reached her Diamond Jubilee.

Street festivities around the globe
Shopkeepers don masks of Queen Elizabeth II and Prince Philip and decorate their store with Union Jack flags in celebration of the jubilee in Brighton, England.

Street parties were organized across England to mark the occasion, prompting hundreds of road closures. The celebrations weren't limited to England, though — a group of 17 Cambridge-based researchers working in Antarctica held "the world's coolest Diamond Jubilee street party" at the Halley Research Station, complete with flags, scones, cakes and ice cream.
