Overview
Two ruins share this stretch of shore on the southeastern side of Achill, where the land meets Achill Sound. The taller of them is Granuaile’s Castle, a 15th-century tower house built by the O’Malley clan and long associated with Grace O’Malley, the sea captain and chieftain the Tudors called the pirate queen. Beside it sits the roofless church, parts of which date to the 12th century, and the old graveyard that holds most of the story here. It is the tower most people come for, but give the graveyard its time – it carries the hardest chapters of the island’s past.
Kildavnet (Irish: Cill Damhnait) means the church of Davnet, after St Dympna (Damhnait), a 7th-century saint said to have fled her father’s incestuous advances and founded a community on this spot. The present church stands on the site of that early one; parts of the walls are 12th-century, much altered, and by the 19th century the building served as a Catholic chapel. Stations of the Cross plaques inside show it is still used for pilgrimage.
The graveyard
The graveyard tells the heavier story. Among the older stones are unmarked graves from the Great Famine (1845–1848). Two memorials mark later disasters: one for the 1894 Clew Bay drowning, when 32 islanders died as their boat capsized on the way to Westport, bound onward to work in Scotland; the other for the ten Achill emigrant workers who died in the 1937 Kirkintilloch fire, a bothy blaze in Lanarkshire. Both losses fell on the same emigration route, a generation apart.
Look too for the grave of Kathleen Kilbane, who died in 1947 aged around twelve, of tuberculosis. Known locally as the ‘Little Saint of Achill’, her grave is still an object of devotion.
What to see
- Granuaile’s Castle – Also known as Kildavnet Tower, this three-storey rectangular tower house was built by the O’Malley clan around 1429 and stands roughly 12 metres tall, with buttressed corners. The tower itself is closed, but from the entrance you can see the remains of the fireplace and floor lines inside. Its position, guarding the narrows of Achill Sound, is the point: this was a place to watch the water from.
- The church ruins – Step inside the roofless nave. A western window looks out to the sea, and there is a long-standing island tradition that ties it to protection from drowning – a belief you understand quickly enough standing in a graveyard full of the drowned.
- St Dympna’s holy well – A short path leads to a stone-lined well by the shore, just outside the graveyard wall. It is still a devotional spot rather than a sight, so treat it accordingly.
- The graveyard – Read the weathered headstones, find the two disaster memorials and Kathleen Kilbane’s grave, and take in the unmarked Famine ground.
Walking nearby
Kildavnet sits on the Achill Heritage Trail, and the Atlantic Drive loop road passes the site. From the ruins you can walk northwest along the shore to the Achill Sound lighthouse, about 1km, or head inland to the headland of An Ceann Ramhar. The Achill Island lifeboat station is a short walk from the castle, by the pier.
Getting There
By car – From Mulranny, take the R319 across the bridge onto Achill Island, then follow the signs onto the L1405 (Atlantic Drive) round the southeast of the island. Park at the small pier that serves the Achill–Clare Island ferry, just past the castle, or in the roadside space opposite the castle. The church and graveyard are a short walk from either.
On foot from the parking – This is not a step-free site. The ground is uneven and there is a stone stile to cross, so wear proper footwear; it is not suitable for wheelchairs or pushchairs.
