Donegal Castle was the former stronghold of the O’Donnells of Tirconell.

The region of Tironnell takes its name from the Irish Tír Chonnaill, deriving from Conall, a son of the legendary High King, Niall of the Nine Hostages. The leading families of the region including the O’Donnells, O’Dohertys and O’Boyles were collectively known as the Cenel Conaill, the ‘Race of Conall’. In the period between the 13th and 17th century, there was an unbroken line of O’Donnell chieftains and kings stretching for over 400 years. The inauguration ceremony of the O’Donnells took place at Kilmacrenan Abbey and the Rock of Doon. 

Unlike the traditional view of monarchy, the chieftain was not always selected based on primogeniture (where the first born son inherits), instead the ruler was selected by the nobles on their fitness to rule. Though occasionally the more subjective view of who exactly is the most fit, could lead to dispute, infighting and long-held grudges.

The oldest part of the castle is the O’Donnell Tower, thought to have been constructed by Red Hugh O’Donnell I, who died in 1505. The English Lord Deputy Sir Henry Sidney who visited the castle in 1566 recounted that

“It is the greatest I ever saw in Ireland in an Irishman’s hands, and it would appear to be in good keeping; one of the fairest situate in good soil and so nigh a portable water as a boat of ten tonnes could come within twenty yards of it.”

The last O’Donnell resident in the castle was the famous Hugh Roe O’Donnell ‘Red Hugh II’, who was one of the key leaders of the rebels in the Nine Years War. After defeat at the Battle of Kinsale in 1601, he sailed to Corunna, Spain where many of the Irish chieftains and their families were seeking exile. He travelled to Valladolid to plead with the Spanish King for assistance to defeat the English in Ireland, only to be fobbed off by King Phillip III who promised help but never acted upon it. Hugh died in 1602 and was buried in Simancas Castle, far from his home in Donegal. Some believe that he was poisoned by the Anglo-Irish double-agent James Blake. With the death of Hugh, the long line of O’Donnells as chiefs and kings of Tirconnell came to an end.
