Killilagh or Killeilagh (Irish: Cill Aidhleach)[1] is a civil parish in County Clare, Ireland.

The small bay of Doolin lies at the boundary between the schistose rocks that form the cliffs stretching southward to the Shannon Estuary and the limestone of the Barony of Burren.

[2] Today it is part of the Catholic parish of Lisdoonvarna and Kilshanny in the Diocese of Galway, Kilmacduagh and Kilfenora.

Parish churches are Corpus Christi in Lisdoonvarna, Holy Rosary in Doolin, Our Lady of Lourdes in Toovahera and Saint Augustine in Kilshanny.

More than 500 men used to work for nine companies at four major quarries: Doonagore, Caherbana, Lough and Moher.

Flag stone from this area was used in English city pavements, the floor of the Royal Mint and for building the Redemptorist Church in Belfast.

Around 85,000 tons were mined in total until, during World War II, the government compulsorily acquired them.

The findings' origins likely are Neolithic (there is a tomb from that period at Teergonean, see above) or even Mesolithic, as those earlier hunter-gatherer groups often used river mouths as locations for their base camps.

The only holy well was one at Toomullin dedicated to Saint Breccan of Arran, a disciple of St Patrick.

A carved stone head from the church is now at the Burren Centre at Kilfenora, after it was stolen in 1971 and later recovered.

The church is mentioned in taxation lists in the early 14th century, but at the time was one of the poorest in the Diocese of Kilfenora.

In 1941, a bronze brooch from around 200 to 300 AD was discovered by workers at Judge Comyn Phosphate digging a new watercourse, the hoard also included a stone ring, two tusks and skull now lost.

The graveyard, the tomb of Conogher MacClancy and the holy well noted by Frost in 1897 are no longer extant.

Hugh's direct descendant, Boetius Clancy (died April 1598), High Sheriff of Clare, owned Knockfin Castle in 1580.

He hanged the survivors of the September 1588 Spanish Armada wreck and had a table made from some of the ship's timber.

Their famous law school was at the site now occupied by the Church of the Holy Rosary (Roman Catholic, c. 1830) at the intersection in Knockfin, about a mile north of Doolin.

Among Francis' regular guests at the house were writer George Bernard Shaw and painter Augustus John.
