Nestled in an inlet of Sheephaven Bay in County Donegal, skirting the wild waters of the Atlantic, stands Doe Castle – the medieval stronghold of the MacSweeneys. The fortress was built in the 1420s. For almost 200 years it served as home, refuge and bastion for at least 13 MacSweeney chiefs – some of whom were party and witness to the most seismic events of Irish history. For example, MacSweeney chief Eoghan Og II gave shelter to survivors of the 1588 Spanish Armada fleet at Doe. The last chief of the castle, Maolmhuire an Bhata Bhui, marched out with Red Hugh O’Donnell, lord of Tyrconnell, to the Battle of Kinsale in 1601. An exquisite carved and ornamented Mac Sweeney grave-slab, dating from 1544, is on show inside the tower house. Display panels onsite chronicle the castle’s history in fascinating detail.
