Places and peoples: nation and region
In terms of natural, as opposed to political geography, it can be argued that Britain is marked by great contrasts but few extremes. Its highest mountain is Ben Nevis (4,406 ft or 1,343 m) in Scotland, its longest river the Severn (220 miles or 354 km) which rises in central Wales but also wanders as far east as Gloucester in England. Its largest lake is Lough Neagh (153 sq miles or 396 sq km) in Northern Ireland. Officially, the mainland stretches from Dunnet Head in the north of Scotland to Lizard point in Cornwall, but most people will describe Britain as running from the famous names of Land’s End, in the south, to John O’Groat’s.
