Donogh More O'Mahony raised the tower around 1430 on a rocky ledge above Dunmanus Bay, giving his house a vertical reach and a corner tower tall enough to watch the water. Crown forces took it in 1602, but the O'Mahonys came back, which suggests the bay and its people still believed the castle belonged to them. A carved head said to be Donogh More was stolen from the north wall in 1972, leaving the ruin with one less face and a new wound.

Built in the 15th or 16th century by the McCarthy family, a prominent Gaelic clan in Munster, Dunmanus Castle is remembered for its strategic location overlooking Dunmanus Bay, which made it a key defensive site during the turbulent medieval period in southwest Ireland.
