A park is any of a number of geographic features. Originally, the term referred to an area maintained as open space where residences, industry and farming were not allowed, often originally so that nobility might have a place to hunt. These were known for instance, as deer parks (deer being originally a term meaning any wild animal). Many country houses in Britain and Ireland still have parks of this sort, which since the 18th century have often been carefully landscaped for aesthetic effect. They are usually a mixture of open grassland with scattered trees and sections of woodland, and are often enclosed by a high wall. The area immediately around the house is the garden. In some cases this will also feature sweeping lawns and scattered trees; the basic difference between a country house's park and its garden is that the park is grazed by animals, but they are excluded from the garden.
