Nestled in a scenic inlet of Sheephaven Bay in the rugged County Donegal, Doe Castle stands proudly as a medieval stronghold that dates back to the 1420s. Built by the MacSweeneys, the fortress served as a home, refuge, and bastion for almost two centuries for at least 13 chiefs of the MacSweeney clan, who witnessed some of the most significant events of Irish history.

Throughout its history, Doe Castle was a witness to both strife and sanctuary. For example, in 1588, MacSweeney chief Eoghan Og II gave shelter to survivors of the Spanish Armada fleet at Doe. And during the Battle of Kinsale in 1601, the last chief of the castle, Maolmhuire an Bhata Bhui, marched out with Red Hugh O'Donnell, lord of Tyrconnell, to defend his people.

Visitors to Doe Castle can explore the fascinating history of the fortress, with display panels onsite that chronicle its past in intricate detail. Additionally, a beautifully carved and ornamented MacSweeney grave-slab dating back to 1544 is on show inside the tower house, providing a glimpse into the art and culture of the time. The castle's location on the wild waters of the Atlantic and its historical significance make it a must-visit attraction for anyone interested in Irish history and culture.
