Hundreds of horses and performers will travel from all corners of the world to the UK in order to perform a celebratory extravaganza for the Queen's Diamond Jubilee.
The idea of the show was based upon the monarch's love of horses and will feature around 500 of the noble creatures.
More than 800 performers are expected to take part, including Inuits from Canada, singers and dancers from Mexico and Cossacks from Russia amongst others.
The event has been aptly named "The World Comes To Windsor" and will take place on the evenings of May 10, 11 and 13.
Ambassadors Angela Rippon and Alan Titchmarsh attended a launch event at the Royal Mews in central London.
"It has been very clear that the Queen's private passion for horses and everything equestrian has spilled over into her public life as our Queen," said Angela.
"And that's why, I think, that the World Comes To Windsor ticks all the boxes."
The Queen also intends to celebrate her 60 years on the throne leading a flotilla of 1,000 boats along the Thames in June 2012.
The flotilla – the largest ever to be assembled on the Thames – will begin in Putney at 2.30pm and arrive at Tower Bride 90 minutes later.
