White Horse - NOT amateur radio

Yesterday I travelled back from Devon by train. After 4 attempts I captured this photo through the train window.

Although the carving in the grass to reveal the white chalk beneath only dates from the 1600s, the Iron Age hill fort above it is thought to be 2000 years old.
