About
A beautifully restored 15th-century Gaelic fortress in the heart of Donegal Town — once the stronghold of the mighty O'Donnell clan, now a fascinating walk through centuries of Irish history.
Things to Do
The Banqueting Hall & Jacobean Fireplace
The first-floor great hall features a magnificent carved stone chimney-piece bearing Sir Basil Brooke's coat of arms, flanked by ornate fruit detailing — one of the finest Jacobean fireplaces in Ireland.
Climb the Trip Stairs
The 540-year-old spiral stone staircase was deliberately built with uneven steps to trip invading swordsmen. It winds clockwise so right-handed O'Donnell defenders had the advantage swinging downwards.
Discover the History Room
On the top floor, information panels chronicle the castle's past from Gaelic lords through the Plantation of Ulster to its 1990s restoration. Scale models show what the full complex once looked like.
Walk the Manor House Ruins & Courtyard
Sir Basil Brooke's Jacobean manor house (1623) stands roofless beside the tower. In the courtyard, spot the Gothic doorways — likely salvaged from the nearby Franciscan friary — and the old ship's mast recalling Donegal's trading past.
Children's Treasure Trail
Pick up a pictorial treasure trail at reception. Kids search for details around the castle while learning about the O'Donnells, making it one of the more family-friendly historic sites in the area.
