Aughnanure Castle

Overview

Aughnanure Castle rises dramatically from a limestone outcrop on the south bank of the Drimneen River, just a few kilometres west of Oughterard. The tower house commands views over Lough Corrib and the surrounding Connemara countryside, making it a natural stop for anyone exploring the western heart of Ireland. Managed by the Office of Public Works and Dúchas, the heritage service, the castle is open to visitors from late February through mid‑November and offers a rare glimpse into a fully intact Gaelic stronghold.

Name and Landscape

The Irish name Achadh na nIubhar means “field of the yews”. A centuries‑old yew tree still stands at the main entrance, a living reminder of the site’s ancient name. The castle’s position on a low limestone peninsula allows the Drimneen River to flow gently beneath the cliff, once enabling supply boats to dock right at the gate – a strategic advantage that helped the O’Flahertys control the waterways of Lough Corrib and the Atlantic coast.

History

The O’Flaherty (Ó Flaithbheartaigh) clan, dominant lords of Iar‑Connacht, are credited with building the present tower house around c. 1500. Some historians suggest an earlier fortification may have been erected by Walter de Burgo, the first Earl of Ulster, after the O’Flahertys were temporarily displaced in 1256. The castle remained the clan’s principal bastion for three centuries, defending against rival Gaelic families and the growing power of the town of Galway. In 1572 Sir Edward Fitton seized the castle and handed it to a junior O’Flaherty who swore allegiance to the English Crown – a move that fractured the clan’s dominance.

During the 17th century the castle changed hands several times, featuring in the 1641 rebellion, the Cromwellian siege of Galway (1652) and later mortgages. In 1952 Peadar O’Flaherty donated the ruin to the State; extensive restoration in the 1960s returned the parapet, chimney and roof to their former condition, and the site reopened to the public in 1974.

The castle is also linked to Grace O’Malley, the famed pirate queen, who married an O’Flaherty (Donal of the Battles). A 16th‑century plaque once hung over Galway’s western gate warning citizens: “From the ferocious O’Flahertys, oh Lord deliver us”.

Architecture Highlights

• Double bawn – An inner wedge‑shaped enclosure surrounded by a larger outer wall with five towers, providing layered defence.
• Watchtower – A circular tower at the south‑eastern corner with a finely corbelled dome and conical stone roof.
• Drawbridge & gatehouse – Remains of a gatehouse and a once‑operational drawbridge guard the north‑western entrance.
• Machicolation & murder hole – Above the eastern doorway a stone over‑hang (machicolation) and a “murder hole” allowed defenders to drop stones on intruders.
• Bartizans & gun‑loops – Small projecting turrets on the third‑floor corners and numerous gun‑loops for muskets.
• Secret chamber – An opening in the garderobe floor leads to a vaulted chamber that once held prisoners.
• Banqueting hall – The ruined hall bears stone reliefs of grapes and vines, hinting at the O’Flahertys’ hospitality and imported wine.
• Dry harbour – Foundations of a harbour indicate the castle’s ability to receive boats directly on the river.
• Underground stream – A water‑spout still feeds a small stream that runs beneath the castle.

These features have led the Heritage Service to describe Aughnanure as “the finest fortified dwelling upon any part of the shores of Lough Corrib.”

Legends and Folklore

Local folklore records four supernatural manifestations: a gamekeeper’s ghost, a rolling head, choking sounds and a banshee wail. A popular tale tells of a trap‑door in the banqueting hall that dropped unwelcome guests into the river below. The stories add an eerie layer to the stone walls, especially after dusk, and are highlighted on the site’s interpretive panels.

What to See & Do

• Climb the six‑storey tower – The narrow spiral staircase leads to the battlements, offering panoramic views across Lough Corrib, the Drimneen River and the Connemara hills.

• Visit the banqueting hall – See the grape‑vine stone reliefs and learn about medieval feasting via interpretive panels.

The castle sits 3.5 km off the N59, just north of Oughterard. It is easily reachable by car; a short, well‑signposted turn leads to the car park. Public transport options include a local bus from Galway to Oughterard, followed by a brief walk. For cyclists, the surrounding roads provide a scenic route along the lake’s western shore.

Nearby Attractions

After exploring the castle, consider a short drive to:

• Brigit’s Garden (≈ 5 km) – a Celtic heritage garden set in native woodland.
• Inchagoill Island (≈ 8 km) – the fourth‑largest island on Lough Corrib, with monastic ruins and walking trails.
• Cong Abbey (≈ 14 km) – the impressive 13th‑century Augustinian abbey.

All are highlighted on the Galway tourism website and make excellent additions to a day‑trip around Lough Corrib.

Visiting Tips & Seasonal Highlights

• Guided‑tour booking – During the main season tours are available every day; in the late season they run on Saturdays and Sundays only.
• Photography – The sunrise over Lough Corrib creates striking reflections on the water; the golden hour highlights the stonework of the outer bawn.
• Family advice – The spiral staircase can be steep; younger children may need assistance.
• Dog owners – Keep dogs on a lead and tidy up after them; they are welcome on the grounds but not inside the exhibition space.
