What is recorded here

Mountjoy Castle stands ruined above Lough Neagh in County Tyrone, where Felim O'Neill of Kinard and Turlough Gruama O'Quinn seized the fort during the Irish Rebellion of 1641. Its broken walls still face the water like a guard who forgot the enemy but never stopped watching. People may have climbed those hills to point at the castle, warn neighbours or simply measure how much power could be taken from a small stone room.
