Windsor Great Park is a Royal Park of 2020 hectares (20.2 square kilometres (5,000 acres)), including a deer park, to the south of the town of Windsor on the border of Berkshire and Surrey in England. The park was, for many centuries, the private hunting ground of Windsor Castle and dates primarily from the mid-13th century. Historically the park covered an area many times the size known as Windsor Forest, Windsor Royal Park or its current name. The park is managed and funded by the Crown Estate, which ran a £0.5 million deficit in 2015, down from £1.6 million in 2006. Most parts of the park are open to the public, free of charge, from dawn to dusk, although there is a charge to enter Savill Garden.
