1. Portumna Castle
Imposing Portumna Castle and Gardens is in a prime location close to the Tipperary County border with stunning views of Lough Derg.
Typical of castles built in the early 1600s, this grand Galway castle was erected by the 4th Earl of Clanricarde and was the home of the de Burgo family for centuries.
Damaged by fire, and roofless from 1826, the castle is currently being restored. Currently, visitors can tour the substantial ground floor which houses an informative exhibition. T
he 17th-century formal gardens and walled kitchen garden were the first Renaissance gardens to be laid out in Ireland and are well worth checking out.
2. Kylemore Abbey (one of the best-known castles in Galway)
Arguably the grandest castle in Galway, Kylemore Abbey is a must-see. It enjoys an idyllic location between Lough Pollaacapull and Druchruah Mountain in the Connemara region of the county.
It was built as a gift from Mitchell Henry to his wife Margaret after they honeymooned in the area. After she died, the neo-Gothic Church was built in her memory.
The abbey was used by Benedictine nuns post WW1 and was a boarding school until 2010. The Victorian Gardens once had 21 glasshouses and fed the castle residents.
They are now beautifully maintained, growing heritage vegetables and, along with the abbey, they are a top visitor attraction in Galway.

Built in 1253 by Meiler de Bermingham it has been the site of many battles, particularly between the Normans and the King of Connaught.
Over the centuries, more defences and floors were added including the trefoil windows, a rarity in Irish castles.
Abandoned in 1596 after being conquered by the O’Donnell clan, it is now under restoration by the Irish Office of Public Works and it’s said to be one of the best castles in Galway to explore.
4. Aughnanure Castle
Aughnanure Castle is a well-preserved Irish tower house, probably built in 1256 by Walter de Burgos, first Earl of Ulster.

This Galway castle was the home of the O’Flaherty clan off-and-on for centuries before being taken over by the Irish Commission of Public Works in 1952 and declared a National Monument. It is now home to endangered Long-eared and Pipistrelle bats.

Access to Menlo Castle is a 30-minute walk from Galway along the riverside path. Local folklore tells of fairies dancing to music in the nearby field.
7. Oranmore Castle
Another Galway icon is Oranmore Castle, a majestic 15th-century tower house that reflects in the still waters of Galway Bay.
Home of the Earl Clanricarde, the 40storey castle has a square staircase turret and a Great Hall. It was a garrison during the 1640s Confederate Rebellion and later owned by the Blake family.
Like many other Galway castles, Oranmore was uninhabited from 1853 until the 1940s when it was bought and restored by Lady Leslie.
Her granddaughter Leonie King (widow of musician Alec Finn of De Danann) now lives there and it is open from June to August.
8. Claregalway Castle
Now fully restored, Claregalway Castle is a 15th-century tower house on the banks of the scenic River Clare.
Its main claim to fame is as the original home of the Brian Boru Harp, Ireland’s national symbol now on display in Trinity College Dublin.
Take a guided tour of this Anglo-Norman tower house, former home of the illustrious Clanricard Burkes. You can stay in private rooms at the Old Mill adjacent to the castle for an authentic experience while exploring more Galway castles.
