On 18 September 2026, Ross Castle will reclaim for one evening some of the atmosphere that once filled its Great Hall. As part of Culture Night, traditional musicians Dean and Brandon Griffin will perform at the top of the medieval tower, overlooking Lough Leane and the Purple Mountains. Heritage Ireland presents the event as an opportunity to hear Irish music once again echoing between the oak roof timbers and stone walls of this hall, which has fallen silent for a very long time.
Music returns to Ross Castle’s Great Hall
Ross Castle is best known for its silhouette on the shores of Lough Leane, a few kilometres from Killarney town centre. But on Friday 18 September, one of the most distinctive events of Culture Night 2026 will take place inside the fortress.
From 7 pm to 8 pm, local musicians Dean and Brandon Griffin will perform in the Great Hall, the room at the top of the tower. The event, entitled Raising the Rafters in the Great Hall, aims to restore one of the room’s original functions: as a place for gathering, entertaining guests and enjoyment.
A hall designed for feasting and celebration
In the 15th century, when Ross Castle was associated with the O’Donoghue Ross clan, this great room hosted feasts and celebrations. Its position at the very top of the tower house still affords remarkable views over Lough Leane and the Purple Mountains today.
Heritage Ireland also highlights the presence of a musicians’ gallery, which has remained unused for a long period. For Culture Night, the venue’s distinctive acoustics will once again become a central part of the visit: its oak roof timbers, limestone floor and massive walls will provide the concert’s resonance.
An echo of everyday life in an Irish castle
The appeal of the evening extends beyond the concert itself. Irish castles are often told through sieges, battles and changes of ownership. This event is a reminder that they were also places of daily life, where people ate, entertained guests, told stories and listened to music.
The Great Hall held an essential place in the social organisation of a tower house. It enabled the clan chief to receive relatives, allies and guests in one of the fortress’s most prestigious spaces.
Ross Castle, the O’Donoghue fortress on the shores of Lough Leane
Ross Castle is believed to have been built in the 15th century by the Irish chieftain O’Donoghue Mór. Its lakeside setting is now one of the iconic images of Killarney National Park.
The fortress also entered history several centuries later, when it became one of the last Munster strongholds to resist Cromwellian forces. A legend held that the castle would fall only when a ship appeared on the lake. Parliamentary commander Edmund Ludlow had a boat brought onto Lough Leane; its presence is said to have helped convince the defenders to surrender.
This dramatic military history has long dominated the story of the castle. The evening of 18 September offers another perspective: that of a lived-in, lively and resonant fortress.
Culture Night transforms Irish monuments for one evening
The Ross Castle concert forms part of Culture Night 2026, held across Ireland on 18 September. For the occasion, several heritage sites managed by the Office of Public Works will offer late openings, concerts, tours, exhibitions and encounters.
In Killarney, the choice of the Great Hall creates a particularly clear dialogue between heritage and living culture. This is not about recreating a 15th-century concert exactly, but about recovering something of the purpose and atmosphere for which the room was designed.
A free evening, but with very limited places
The concert will take place on Friday 18 September 2026, from 7 pm to 8 pm. Admission is free, but Heritage Ireland specifies that places are strictly limited and advance booking with Ross Castle is essential. Tickets are allocated in order of request, with a maximum of two bookings per person.
The intimate nature of the event is easy to understand: the Great Hall is at the top of the tower and is reached via the castle’s spiral staircases. Heritage Ireland warns that these uneven steps may be difficult for people with mobility issues.
A different way to discover Ross Castle
For those who already know Ross Castle from the shores of Lough Leane, the evening offers above all an unusual opportunity to imagine the monument differently. A medieval fortress was not merely a matter of defensive walls and arrow slits: behind the stone, a genuine social life unfolded.
When the first notes ring out beneath the Great Hall’s roof timbers on 18 September, they will not, of course, recreate the O’Donoghue evenings exactly as they were. But for one hour, they will restore to this medieval space a function it has long lost: that of a place where people gather to listen to music.
