Castles in County Galway

Water shapes most of this list. Aughnanure, the six-storey O’Flaherty tower near Oughterard, stands on the shore of Lough Corrib, and Ashford Castle holds the top of the same lake at Cong on the Mayo border, where day visitors pay to walk the 350 acres. Kylemore Abbey sits under Duchruach Mountain with its own lake, walled garden and woodland paths.

The rest runs from ruins you can walk up to freely to buildings still in use. Clifden Castle, John D’Arcy’s roofless Gothic Revival manor above Clifden Bay, lies at the end of a 1 km gravel track off the Sky Road, free and unstaffed. Lynch’s Castle in the middle of Galway city is a working AIB branch with history panels on the ground floor. Menlo Castle’s grounds are closed for conservation, so the ivy-covered shell is best seen from the greenway across the Corrib.

Distances matter here. Connemara alone takes a day, with Ballynahinch at Recess and Kylemore an hour or more from the city, while Portumna, whose Jacobean ground floor and walled gardens sit beside a forest park on Lough Derg, is right across the county in the east. Glinsk, in the Suck valley near the Roscommon border, is a detour rather than a stop. Dunguaire at Kinvara has been shut since 2023, so treat it as a photograph.

Dunguaire Castle – tower on Galway Bay

Kinvara, galway

Dunguaire Castle, a 75-foot tower house built by the O'Hynes clan around 1520 on the shore of Galway Bay, has been shut since 2023 in a funding dispute, so tours and the medieval banquet are on hold. Its fame is older than the closure: Oliver St John Gogarty bought it in 1924 and filled it with Yeats, Lady Gregory and Shaw, and its silhouette is one of the most photographed in Ireland.

Glinsk – one of Ireland's last castles

Glinsk, galway

Glinsk is a small farming village near the Galway–Roscommon border, in the valley of the River Suck. Its landmark is Glinsk Castle, a roofless tower house from the early 1600s, often called one of the last castles built in Ireland and known for its tall five-shafted chimney stacks. The ruined Ballinakill Abbey, with a carved Burke effigy, lies nearby.

Menlo Castle – Blake's ivy-clad Corrib ruin

Menlo, galway

Menlo Castle is the ivy-covered shell of a Blake family mansion that burned on a July night in 1910, killing two maids and the family's daughter Eleanor, whose body was never found. The grounds are closed for conservation, but the ruin still holds the east bank of the River Corrib. The clearest view is from the greenway on the far side, near the NUI Galway sports grounds at Dangan.

Portumna – Jacobean castle and forest park

Portumna, galway

Portumna Castle is a semi-fortified Jacobean house, built before 1618 for the Earls of Clanricarde and gutted by fire in 1826; only the restored ground floor is open. Beside it lie formal gardens and a walled kitchen garden, and a short walk away a forest park runs down to Lough Derg, home to fallow deer and nesting white-tailed sea eagles.

Portumna Castle – Jacobean house & gardens

Portumna, galway

Portumna Castle is a rare Jacobean house at the point where the Shannon widens into Lough Derg, built between 1610 and 1618 and gutted by fire in 1826. The state has been restoring it since the 1960s; today the ground floor and the formal walled gardens – including a living willow maze – are open, with a 600-hectare forest park next door.

Questions people ask

Can you go inside Dunguaire Castle?
Not at present. It has been closed since 2023 in a funding dispute, so the tours and the medieval banquet are on hold. You can still walk out along the shore at Kinvara and see the tower from the water's edge, which is what most people come for.
Which Galway castles are free to visit?
Clifden Castle is open ground year-round at the end of a 1 km gravel track off the Sky Road, with no facilities of any kind. Lynch's Castle in Galway city is an AIB branch, so you can walk in and read the ground-floor history panels.
Where do they cluster?
In three groups. Lough Corrib has Ashford at Cong, Aughnanure near Oughterard and Menlo on the city's edge; Connemara has Kylemore, Ballynahinch at Recess and Clifden; east Galway has Portumna on Lough Derg and Glinsk near the Roscommon border.
Which one is best if you want gardens as well as the building?
Kylemore Abbey, for the restored walled garden and the lakeside woodland walk, or Portumna Castle, where the Jacobean ground floor opens onto formal walled gardens with a living willow maze and a forest park running down to Lough Derg.
Are any reachable without a car?
Lynch's Castle stands on a main street in Galway city. Dunguaire is at the edge of Kinvara village, and Oranmore's castle sits on the bay ten minutes east of the city. Connemara and east Galway both need a drive.
