The hill, topped by Banwell Camp, an Iron Age hillfort, covers the corners of four square. The "large multivallate hillfort ... is the western example of three hillforts occupying outcrops of carboniferous limestone on the north-western fringe of the Mendip Hills" https://www.historicengland.org.uk/listing/the-list/list-entry/1008031 . On the left can be seen the line of the former Strawberry Line passing Sandford. At ST405596, among the darker fields on the right, a new solar farm symbol appears on the 1:25000 map, the first time I've noticed it.
