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 such a 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."
