Overview
Inis Cealtra, literally the island of burials, is better known as Holy Island. It lies in the clear waters of Lough Derg, about 1 km from the mainland and 2 km north‑east of Mountshannon, County Clare. The 50‑acre island is uninhabited, owned by Clare County Council and conserved by the East Clare Heritage Centre. Visitors reach it by a short boat trip from Mountshannon harbour, joining a tradition that once formed part of the “Jewel of Lough Derg” pilgrimage route.
History / Background
- Foundations (c. 520‑mid‑6th c.) – A hermitage was founded by St Colum (d. 548) and later expanded by St Caimin (d. 653), who became Bishop‑Abbot of Inis Cealtra and possibly the first Bishop of Killaloe.
- Monastic growth – By the 7th century the island was recognised as an “asylum of Ireland”, hosting a thriving school of learning and a community of saints and scholars.
- Viking attacks – Norse raids in 836, 922 and again in 934 burned parts of the settlement, but the monks rebuilt, aided later by the brother of High King Brian Boru, who commissioned at least one new church.
- Later centuries – The monastic complex survived until the 13th century, after which the churches fell into ruin following the Reformation. The island remained a burial ground; even today coffins are ferried across the lake for interment.
- Pilgrimage peak – In 1608 the shrine was granted a plenary indulgence by Pope Paul V, and records show 15 000 pilgrims visited within two years. The tradition waned after the Great Famine of the 1840s but the ruins continued to attract scholars and tourists.
- Folklore – The iconic 80‑ft (≈ 24 m) round tower was never roofed; excavations by Dr Liam de Paor in the 1970s confirmed no conical cap stones existed. Local legend blames a witch’s curse on the mason. A “bargaining stone” with a central hole is said to have sealed marriage vows, and tales of hidden souterrains persist despite lack of archaeological proof.

Visiting Holy Island
Getting there
Boats run regularly from the harbour at Mountshannon during the tourist season. The crossing takes roughly 5‑10 minutes and is operated by local providers; tickets are purchased on‑site. There is a small car park adjacent to the harbour, making it easy to combine a drive along the Lough Derg shoreline with a visit to the island.
Visitor centre
The East Clare Heritage Centre in Mountshannon opens 9:00‑17:00 Mon‑Sat and 10:00‑16:00 Sun (subject to seasonal variation). Exhibits explain the island’s monastic past, the pilgrimage tradition and the natural history of Lough Derg. A café and restroom facilities are available here; there are no amenities on the island itself, so bring water and a snack if you plan to spend time exploring.
Family‑friendly tips
