Over in Dover, whence the train takes the Chunnel under the channel, we have one of England’s more iconic sites, the White Cliffs. Located at the point on England nearest to the continent, these chalk cliffs stand out in stark white defiance to France, from whose shores they are easily seen. Before air travel, for millennia, these cliffs were either the first or last view a traveller would have of the sceptered isle. The cliffs are geological formations composed of chalk. Much of southern England’s natural landscape lies on a chalk foundation… and there are some very interesting prehistoric carvings throughout the region, right in the side of hills, which are also worth a look.
