The once beautiful Gaelic Celtic castle of the O'Donnells, along with their extensive lands, was subsequently granted to an English military Captain in 1610.
Captain Basil Brooke, later Knighted, had played a significant role in the overthrow of Gaelic Ireland.
The Castle's Unique Renovation
Brooke's Jacobean extension to the Celtic castle
The English captain built himself a manor-house, as an
extension onto the south-western side of the O'Donnell castle.
The captain also
renovated the castle itself.
A Jacobean Twist
The new manor-house, along with the modifications to the castle, added a unique jacobean-style twist to the original Celtic look of the castle.
Donegal Castle was, at that time, already almost 140 years old.
The Rewards Continue
addition to the O'Donnell castle and lands, Sir Basil Brooke received the ruined shell, and accompanying lands, of the Donegal friary.
The Knighted Captain used the scattered stones from the sacred ruins of the abbey to refurbish Donegal Castle.
The Jacobean style of architecture is associated with English Monarch, King James I. He ruled from 1603 to 1625.
The style contained elements of Dutch and German influence.
Customs and Excise 'Rights'
Sir Basil Brooke was also given English Crown-imposed Customs
and Excise 'rights' over the River Eske from the castle to Donegal Bay.
The river Eske was an abundant source of
Donegal Castle Abandoned
The O'Donnell Castle Donegal Town was occupied by Sir Basil Brooke until his death in 1633.
After his death, the estate passed to his son Sir Henry Vaughan Brooke, Member of the English Parliament governing Donegal County. Vaughan Brooke was in possession of further estates in neighboring County Fermanagh.
After several more transfers the neglected castle was eventually abandoned.
