I suppose we are lucky here in that a lot of the prehistoric monuments - Neolithic long barrows, Bronze Age round barrows, Iron Age hillforts - are on hilltops, and managed to escape the plough. They were instead used for grazing livestock, and some of them are astonishingly well-preserved. There can be an eerie sense of connection, walking the ramparts of an Iron Age hillfort, and knowing that someone was making that same circuit two thousand years ago.

We do less well preserving 19th and 20th architecture in our towns. All sorts of interesting buildings get pulled down when the developers flash the cash.
