Kilcoole

Evidence of ancient settlement in the area includes a number of fulacht fiadh, bullaun and holy well sites in the townlands of Kilcoole, Kilquade and Ballycrone. Kilcoole Church, close to the centre of Kilcoole, is reputed to date to the 12th century and is a protected national monument.

Next to Kilcoole railway station (built c. 1855) is a monument commemorating the landing of 600 rifles and ammunition for the Irish Volunteers on board the Chotah by Sir Thomas Myles in August 1914. It is eclipsed by accounts of the contemporary landing of Volunteer's arms at Howth on board the Asgard. On 1 August 1914, 600 Mauser rifles and 20,000 rounds of ammunition were landed at the beach in Kilcoole. The arms and ammunition was smuggled using Myles's boat during the night. When the arms were landed they were removed on bicycles and in vehicles by volunteers. The arms were taken to Pádraig Pearse's school, St Enda's, in Rathfarnham, County Dublin.
