What is recorded here

Ballygrennan Castle and its surrounding pasture hold a hidden circular earthwork that resisted every human attempt to see it. Men walked the grass, drew maps and took photographs from above, yet the circle stayed absent until a gas pipeline survey revealed its ghostly shape. The land kept its own secret, waiting for the right moment to show itself. What was built there, who forgot it and why it resisted discovery remain unknown.
