Windsor Great Park (locally referred to simply as the Great Park) is a large deer park of 5,000 acres (20 km2), 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. Now largely open to the public, the parkland is a popular recreation area for residents of the western London suburbs. It is owned and managed by the Crown Estate.
