A Stronghold of the Mac Sweeneys
Built in the early 15th century, Doe Castle became the stronghold of the Mac Sweeney clan, who arrived from Scotland as gallowglass warriors—elite mercenaries in service to Irish chieftains. From here, they ruled much of northwest Donegal, and the castle’s position was ideal for controlling sea routes and inland trade.
Surrounded by water on three sides and protected by thick walls, Doe was built to last. And last it did—through clan rivalries, sieges, and shifting allegiances during turbulent centuries of Irish history.
A Castle of Legends
Local lore is never far from the stone walls of Doe Castle. One of the most romantic tales tied to the site is the love story between Aileen Mac Sweeney, daughter of the clan chieftain, and Turlough Óg O’Boyle, the son of a rival. Forbidden love, midnight escapes, and heartbreak all swirl around the castle’s history, lending a certain haunting beauty to the place.
The poet William Allingham, who grew up nearby, often walked the grounds and referenced the castle in his writing—adding a layer of literary charm to its rugged appeal.
Exploring the Castle
While much of the interior is no longer accessible, the restored tower house is a commanding presence, and guided tours are sometimes available during the summer months. Even if the gate is closed, the surrounding grounds are freely open to the public, and the setting alone is worth the visit.
Walk along the shore, take in the panoramic views of Sheephaven Bay, and enjoy the tranquility that surrounds this timeless place. Photographers will find endless inspiration here, especially at sunrise or sunset when the castle’s silhouette reflects off the calm waters.
Practical Tips
Doe Castle is located just outside the village of Creeslough, with clear signposting from the main road. There’s a small car park, and the walk to the castle is short and flat. It’s a great stop if you’re exploring the Wild Atlantic Way or heading toward Glenveagh National Park.
Facilities are limited at the site, so bring your own snacks or plan a stop in one of the nearby towns for a bite and a warm cup of tea.
If you’re visiting on a Sunday in summer, time it for a local concert—traditional music is occasionally played on the castle grounds, offering an unforgettable way to experience both the culture and setting in one go.
