Carrickmines Castle

Carrickmines Castle guarded the southern edge of the Pale until English forces massacred over three hundred defenders in 1642, leaving human remains trapped inside its bedrock defences. The M50 motorway later cut through the site, forcing activists to camp on the ruins and preserve sections of the medieval walls beneath modern roundabouts. Speed now flows over graves and stone, turning a bloody frontier into a passing shadow for drivers who never know they are racing across a graveyard.
