The Queen's 90th birthday is shaping up to be a celebration of monumental proportions as the longest-reigning British monarch will toast the milestone with 25,000 guests over four nights of festivities at Windsor Castle. Tickets for the events, which will include 900 horses and 1,500 performers, went on sale on Nov. 24.

Buckingham Palace has announced that the birthday celebrations, hosted in Windsor's Home Park, will involve performances from dancers, musicians and choirs, along with well-known artists and actors.

Tickets to the celebrations cost between $110 and $330 on the first three nights and rise to between $150 and $395 on the final night. A free ballot for tickets to a pre-show party on the Long Walk, which leads through the park to Windsor Castle, will open early next year. Another 5,000 free tickets will be made available to watch the final show on a giant screen in Windsor.

The Queen will also host a street party on The Mall in June.

Simon Brooks-Ward, producer and director, said, "We've been working hard to make this a most unique birthday celebration. We're especially delighted with our plans to offer an extra 5,000 people the chance to be part of the celebrations through our balloted system for tickets on the Long Walk. This will take place in the new year."

The Queen, who turns 90 on April 21, will also mark the milestone day with the biggest street party ever on The Mall in London on June 12. It was confirmed in July that 10,000 guests will be invited to the quintessentially British celebrations, set to be attended by the Queen and Prince Philip along with her grandsons princes William and Harry and other members of the Royal Family.

Other commemorations set to take place on the weekend of the Queen's official birthday in June include a service of thanksgiving at St. Paul's Cathedral and Trooping the Colour.
