Creggan Church Yard, near Crossmaglen is home to some of Ireland's best known Gaelic poets. The current Church of Ireland church dates back to 1731 but there is evidence to suggest an earlier Catholic church preceded it. This is the burial place of three 18th century Irish poets: Art Mac Cumhaigh, Pádraig Mac Aliondain and Séamus Mór MacMurphy. It is also the burial place of the clan O’Neill. The O’Neills of Tyrone attempted to retake South Armagh from the invading English during the middle of the 15th century. The burial place was re-discovered in 1971 during a cleanup of the cemetery for the proposed bi-centennial celebrations of Art MacCooey. It is reputed the O’Neills arrived in Creggan in 1447 and the burial place currently contains approximately 70 skulls.
