Aideen's Dolmen

Aideen's Dolmen is a Neolithic portal tomb on the Howth peninsula north of Dublin, dating to around 2000 BCE. It takes its name from Aideen, a figure of Irish mythology said to have been buried here after dying of grief when her husband Oscar was slain at the Battle of Gabhra — a tale recorded in early Irish literature. The structure consists of a large capstone resting on upright orthostats, a form of megalithic construction that predates the Egyptian pyramids by centuries and is found across the Irish landscape. Today the dolmen sits quietly on the wooded ridge of Howth Head, largely unmarked and well off the main visitor trail — a genuinely overlooked prehistoric monument.
