And one I had looked for traces of (online and in person) but come a blank until I realised it was known under a different name: Map [or Covering Ground] (1991) by Anna Best
It was meant to be an upside down ’cast’ of a hilltop made in wood.
I remember visiting this with my family and grandparents as a kid and being taken with how huge it seemed.
