Oxford has a total area of about 46 sq km (17.6 sq miles). While parts of the urban area are very densely developed, 52% of the city is actually open space.
Some 27% of Oxford is in the Green Belt, with much of this land being flood plain. The historic city parks and nature conservation areas (including a Special Area of Conservation and several sites of special scientific interest) create pockets and corridors of green within the City boundary. Information on greenspaces can be found on the Ordnance Survey webpage.
