The four furthest-flung extremities of mainland Britain are:

Land's End and John O'Groats are commonly accepted as the furthest points on the mainland which can be travelled on public roads, being 874 miles apart. Actually, Duncansbury Head is slightly further East by one and a half miles, but everyone knows John O'Groats better, while Ardnamurchan Point just beats Land's End to the furthest point west.

Traditionally, the centre of England is marked by a medieval cross on the village green at Meriden in Warwickshire.
