Ardamullivan Castle is a restored tower house consisting of six storeys. Although there is no history of the exact date of when the castle was built, it is believed it was built in the 16th century as it was first mentioned in 1567 due to the death of Sir Roger O’Shaughnessey who held the castle at the time. 

Sir Roger was succeeded by his brother Dermot, ‘the Swarthy’, known as ‘the Queen’s O’Shaughnessy’ due to his support shown to the Crown. Dermot became very unpopular among the public and even among his own family after he betrayed Dr Creagh, the Roman Catholic Archbishop of Armagh, who had sought refuge in the woods on O’Shaughnessy territory. 

Tensions came to a boil in 1579, when John, the nephew of Dermot, fought with Dermot outside the south gate of the castle in dispute over possession of the castle. Both men were killed in the fight. After this period the castle fell into ruin until the last century where it was restored to it’s former glory.
