🏛️ Attraction

Last updated: 4 March 2026

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, the castle is open to visitors from late February through mid‑November and offers a rare glimpse into a fully intact Gaelic stronghold.

History

The O’Flaherty (Ó Flaithbheartaigh) clan, once the dominant Gaelic lords of Iarchonnacht, erected the original tower house around 1490. For four centuries the family used Aughnanure as a political and military hub, controlling the waterways of Corrib and the Atlantic coast. In 1572 Sir Edward Fitton captured the castle and granted it to a junior O’Flaherty who recognised the English Crown – a move that fractured the clan’s power. The castle later changed hands during the 1641 rebellion, the Cromwellian siege of Galway (1652) and a series of mortgages before being donated to the State by Peadar O’Flaherty in 1952. A comprehensive restoration programme in the 1960s returned the stonework, crenellations and machicolations to their former glory, and the site reopened to the public in 1974.

What to See & Do

  • Six‑storey tower house – Climb the narrow spiral staircase to reach the battlements. From the top, the panorama stretches across Lough Corrib, the Drimneen River and the rugged Connemara hills.
  • Double bawn and round watchtower – Aughnanure is one of the few Irish castles with a double bawn enclosure, a defensive feature that gave the O’Flahertys an extra layer of protection.
  • Banqueting hall – The ruined hall is famed for its stone reliefs of grapes and vines, a testament to the clan’s hospitality. A concealed trap‑door, known locally as the “flagstone of treachery”, once dropped unwelcome guests into the river below.
  • Underground stream and dry harbour – An underground water‑spout still feeds a small stream that runs beneath the castle, while the remains of a dry harbour hint at the O’Flahertys’ maritime connections.
  • Great kitchen discovery – Recent aerial surveys (2018) revealed the footprint of a 16th‑century kitchen building that once served the banqueting hall. Although the structure is no longer visible, interpretive panels explain its role in medieval feasting.
  • Haunted tales – Local folklore records four supernatural manifestations: a gamekeeper’s ghost, a rolling head, choking sounds and a banshee wail. The stories add an eerie layer to the stone walls, especially after dusk.
  • Family‑friendly exploration – The castle’s battlements, bartizans and hidden nooks provide endless opportunities for children to play hide‑and‑seek while learning about Gaelic history.

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.

Accessibility While the historic fabric limits full wheelchair access, the ground‑level exhibition area and the visitor centre are reachable via a smooth path. Limited access signage is posted throughout the site, and staff are on hand to assist where possible.

Nearby attractions After exploring the castle, consider a short drive to Corrib Cruises for a boat tour of Lough Corrib, or visit the Knockillaree Riding Centre for an authentic Connemara equestrian experience. Both are highlighted on the Galway tourism website.
