A bishop of Ardmore swore fealty to Henry II of England at Cashel, as a suffragan of its archbishop, in 1171.

The last reference to an independent bishop of Ardmore dates to 1210, when Innocent III listed it as one of Cashel's eleven suffragan dioceses.

[7] No longer a residential bishopric, Árd Mór is today listed by the Catholic Church as a titular see.

On a hill above the village is a well-preserved 30-m-high, 12th-century round tower and the ruins of a cathedral dating from the 12th and 13th centuries[9][10] with an adjacent 8th-century oratory.

One of the outer walls of the cathedral features some stone carvings retrieved from an earlier 9th-century building.

[citation needed] Harbour development remains unfunded and larger fishing vessels are unable to utilise the present docking facilities due to a lack of water depth.

[citation needed] The Samson, a crane ship, was wrecked on Ram Head, near the village, during a December storm in 1987 as it was being towed from Liverpool to Malta.

The village includes two hotels, a number of pubs and restaurants, a seasonal petrol station, a pier and slipway, and one store.

The cliff walk, which has marker posts erected along the route, passes an old remodeled Coastguard Station, St Declan's Cell and Holy Well, a ruined church, the wreck of the Samson, an abandoned 20th century coast guard lookout, and another, much older, lookout tower.

[citation needed] Ardmore is served on a daily basis by Bus Éireann route 260 which links it to, inter alia, Youghal, Midleton and Cork city.
