Trig point within Bartine Castle, Bartinney Downs

Trig point within Bartine Castle, Bartinney Downs is a castle, fort or tower in Cornwall, England. Perhaps the stone marker still stands where the castle collapsed, waiting for a surveyor who never returned. Maybe the downs hide a chamber where wind speaks in voices lost before writing. Imagine a hand placing the point not for measurement but for memory, anchoring forgotten shape against the sky.
