Closed for works: Aughnanure Castle is temporarily closed to the public from 22 June 2026 while the car park is upgraded. No reopening date has been confirmed – check Heritage Ireland before you travel.
Overview
Aughnanure Castle is the best-preserved late-medieval tower house in Connemara, and what sets it apart is the double bawn – two walled enclosures, one inside the other – which almost no other Irish castle still has. It stands on a rocky spur where the Drimneen River narrows, just west of Oughterard, and was the headquarters of the O’Flaherty clan, the lords of Iar-Connacht. The Office of Public Works runs it, and in a normal year it opens from late February to mid-November – though see the closure notice above before planning a 2026 visit.
Name and Landscape
The Irish name Achadh na nIubhar translates to “field of the yews”. A veteran yew tree still stands at the main entrance, a living link to the site’s name. The castle occupies a strategic limestone spur where the Drimneen River narrows, a position that let the O’Flahertys control movement between Lough Corrib and the country around it. Foundations of a dry harbour survive below the walls, a reminder of how much the stronghold depended on the water.
History
The O’Flahertys (Ó Flaithbheartaigh) built the tower house and inner bawn in the late 15th century, adding the outer bawn, banqueting hall and other buildings in the 16th – so the castle you see went up in at least two phases. Some evidence suggests an earlier fortification stood here, raised by Walter de Burgo after the clan was temporarily displaced in the 13th century. For three centuries, Aughnanure was the clan’s principal bastion, defended against rival Gaelic families and the encroaching power of the merchant town of Galway.
The castle’s history took a sharp turn in 1572 when Sir Edward Fitton seized the stronghold and handed it to a junior O’Flaherty who pledged allegiance to the English Crown. This act fractured the clan’s unity and weakened their hold on the region. The castle later changed hands during the 1641 rebellion and the Cromwellian siege of Galway. In 1952, Peadar O’Flaherty donated the ruin to the State. Extensive restoration in the 1960s rebuilt the parapet, chimney, and roof, and the site reopened to the public in 1974.
The castle is also linked to Grace O’Malley, the famed sea captain of Clew Bay, who married Donal an Chugaidh O’Flaherty here in 1546 – a match that joined the O’Flaherty motto, ‘Fortune favours the strong’, to the O’Malley one, ‘Powerful by land and by sea’. The O’Flahertys were feared neighbours; a plaque once hung over Galway’s western gate warning citizens: “From the ferocious O’Flahertys, oh Lord deliver us.”
Architecture Highlights
Aughnanure is renowned for its defensive sophistication, particularly the double bawn – an inner wedge-shaped enclosure surrounded by a larger outer wall with five towers. This layout forced attackers to breach two lines of defence before reaching the tower house.
Key features include:
- Watchtower: A circular tower at the south-eastern corner with a finely corbelled dome and conical stone roof.
- Machicolation and Murder Hole: Above the eastern doorway, a stone overhang and a hole in the floor allowed defenders to drop stones or boiling liquids on intruders.
- Banqueting Hall: The ruined hall features stone reliefs of grapes and vines, indicating the O’Flahertys imported wine and hosted lavish feasts.
- Secret Chamber: An opening in the garderobe floor leads to a vaulted chamber used for prisoners or secure storage.
- Bartizans and Gun-loops: Small projecting turrets on the third floor and narrow slits for muskets provide overlapping fields of fire.
- Drawbridge and Gatehouse: Remains of the gatehouse and drawbridge guard the north-western entrance.
- Underground Stream: A water-spout still feeds a small stream that runs beneath the castle, providing a fresh water source.
Legends and Folklore
Local folklore adds an eerie layer to the ruins. Stories tell of a gamekeeper’s ghost, a rolling head, and the wail of a banshee. The most popular tale involves a trapdoor in the banqueting hall that supposedly dropped unwelcome guests into the river below. While likely a fabrication to deter enemies or scare servants, the story gives the hall a reputation for treachery. Interpretive panels on site explore these legends alongside the historical record.
What to See & Do
- Climb the Tower: The narrow spiral staircase leads to the battlements, offering panoramic views across Lough Corrib, the Drimneen River, and the Connemara hills.
- Explore the Bawns: Walk the perimeter of the double bawn and examine the watchtower, a unique defensive feature in Irish castles.
- Visit the Banqueting Hall: View the grape-vine reliefs and learn about medieval feasting and the O’Flaherty lifestyle.
- Discover the Harbour: See the dry harbour foundations and the underground stream that sustained the garrison.
- Family Exploration: The open layout, battlements, and hidden nooks make the castle engaging for children. The spiral staircase offers a safe climb for older kids.
- Photography: The elevated position and river setting provide excellent photo opportunities, particularly at sunrise when the light reflects off the water.
Practical Information
Opening Hours
The castle is temporarily closed from 22 June 2026 for car-park works; no reopening date has been set. When open, the season runs 27 February to 18 November:
- 27 Feb – 28 Oct: 9:30am – 5:00pm (last admission 4:15pm).
- 29 Oct – 18 Nov: 9:30am – 4:00pm (last admission 3:15pm).

- Family (2 adults + 2 children): €13.00
- Free on the first Wednesday of each month, and for OPW Heritage Card holders.
Facilities and Access
- Parking: Free car parking and a dedicated coach park on site, a short walk from the castle along the river.
- Accessibility: The visitor centre and ground-level exhibition are accessible on a smooth path. The tower stairs are steep and uneven, so the upper floors are not wheelchair accessible.
- Toilets: Public toilets are near the visitor centre.
Getting There
The castle is signposted off the N59 just north of Oughterard, with a short turn to the car park. By public transport, take a bus from Galway to Oughterard, then walk.
Nearby Attractions
At the far, northern end of Lough Corrib, Ashford Castle near Cong is a very different beast – a 13th-century castle turned luxury hotel, set in extensive parkland. Oughterard, the angling village 3.5 km east, is the nearest place for food and fuel, and the road on west runs into Connemara proper.
Visiting tips
- Stairs: The spiral staircase is narrow and steep. Younger children need a hand, and anyone with mobility issues should stay on the ground level.
- Best light: Early morning brings clearer views, fewer people, and softer light on the stonework.
- Go on a first Wednesday if you can – admission is free then, and for OPW Heritage Card holders any day. When the site reopens after the car-park works, confirm the season’s hours on the official website before setting out.
