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.
