A world heritage site, Henry VIII introduced deer for hunting in the park, but not all were caught and so they continue to live there to this day.
It is the home of the famous royal observatory, which sits at the top of the park's hill.
It is also host of some of the most spectacular views in the capital, from Westminster to Canary Wharf.
The modern boundary to the park was built by James I in the sixteenth century for £2,000.
It has been used for a range of events over the years, and has also been used as a scene for films such as The Young Victoria.
In 2006 Greenwich Park hosted the Tour of Britain cycle race, and it also stages the Greenwich Meridian 10k each year.
Greenwich Park's hosting of Olympic events has been met with resistance from locals, and as a result Games planners have ensured that ancient trees will not have to be removed for the equestrian.
It will hold 10 events across jumping, dressage, eventing, modern pentathlon and paralympic equestrian
