What is recorded here

Ballygrennan Castle and the nearby earthwork share one quiet demesne, but the smaller circle never appeared on historic maps and may have vanished entirely. It resisted human memory, hiding inside pasture and shadow until a gas-pipeline flight caught a pale ring in 1984. After that it became a picture rather than a place, bright in one frame and absent in every later view. The land kept its secret, giving up only the least possible shape of what it had swallowed.
