Saturday 4 January 2020. On a cold, overcast day we set out for Bratton Camp, an Iron Age hillfort located just to the east of the town of Westbury, in Wiltshire. Under the western rampart of the hillfort is the Westbury White Horse, one of a number of hill figures carved over the centuries into the chalk downs of southern England. Bratton Camp is more than 2000 years old and encloses Neolithic and Bronze Age barrows; Westbury White Horse is probably around 300 years old. The bleak, dichromatic landscape was profoundly beautiful, an immensity of grass and sky. Even a sub-zero gale did not diminish the sense of joy we experienced.
