|England comprises the central and southern two-thirds of the island of Great Britain, plus offshore islands of which the largest is the Isle of Wight. It is bordered to the north by Scotland and to the west by Wales. It is closer to continental Europe than any other part of Britain, divided from France only by a 38 km sea gap.
Most of England consists of rolling hills, but it is more mountainous in the north with a chain of low mountains, the Pennines, dividing east and west. The dividing line between terrain types is usually indicated by the Tees-Exe line. There is also an area of flat, low-lying marshland in the east, much of which has been drained for agricultural use.
The list of England's largest cities is much debated because in English the normal meaning of city is "a continuously built-up urban area"; these are hard to define and various other definitions are preferred by some people to boost the ranking of their own city. However, by any definition London is by far the largest English city. Manchester and Birmingham now vie for second place. A number of other cities, mainly in central and northern England, are of substantial size and influence. These include: Leeds, Liverpool, Newcastle, Sheffield, Bristol, Coventry, Leicester, Nottingham and Hull.
The Channel Tunnel, near Folkestone, directly links England to the European mainland. The English/French border is halfway along the tunnel.
The largest natural harbour in England is at Poole, on the south-central coast. Some regard it as the second largest harbour in the world, after Sydney Australia, although this fact is disputed (see harbours for a list of other large natural harbours).
