As night falls, Drogheda’s medieval monuments take on a new face. The Lú Festival of Light turns the historic centre into an open-air trail of light, with monumental projections bringing Irish folklore’s myths, heroes and creatures to life. The 2026 edition will take place from 23 to 26 October, a few days before Halloween, in the heart of County Louth.
The idea is as simple as it is appealing: explore Drogheda’s streets on foot and discover audiovisual creations projected onto several landmark buildings. The main event is free and requires no ticket. It is aimed at families and anyone with an interest in heritage, Celtic mythology or digital arts.
The Lú Festival of Light does not take place in a hall or enclosed venue. It takes over Drogheda’s town centre, using the city’s architecture as a storytelling canvas. Facades, towers and ancient gates become immense screens through projection mapping, a technique that precisely adapts images to the shape and dimensions of a building.
For 2026, the trail will notably showcase three major sites: Old Abbey, St Peter’s Church and St Laurence’s Gate. These monuments are close enough to connect on foot. Visitors can therefore follow the route at their own pace, pause at each sequence and enjoy the atmosphere of the town centre between projections.
The GPS point given on this listing corresponds to Old Abbey, one of the main official stops. It is a useful landmark from which to begin exploring, although the festival extends well beyond this single monument.
Old Abbey is among the festival’s most striking settings. The remains of the former Augustinian abbey of St Mary d’Urso, founded in the early 13th century near Mary Street, include a Gothic bell tower particularly well suited to vertical projections. Once night falls, the stone almost disappears beneath the colours, silhouettes and effects of depth.
The light installations draw on ancient stories linked to Drogheda, the Boyne Valley and the Irish imagination. Gods, warriors, fabulous animals and shape-shifting creatures appear on the tower in a staging where image, music and architecture work together.
Located on Drogheda’s main shopping street, St Peter’s Church forms another key stop on the trail. Its elaborate facade allows for visual effects very different from those presented at Old Abbey. The projections seem to open up the building, shift its columns or conjure imaginary settings from the stonework.
The church should not be confused with the medieval site of St Peter’s Church of Ireland, located nearby. The one on West Street is best known for housing the relic of Saint Oliver Plunkett. During Lú, its facade becomes a meeting point between Drogheda’s religious heritage and the mythological tales celebrated by the festival.
Built in the 13th century, St Laurence’s Gate is one of Drogheda’s best-preserved medieval monuments. Its two imposing towers once formed a strategic entrance to the walled town. The festival makes use of this spectacular silhouette to turn it, in an almost literal sense, into a gateway to the world of Irish legend.
The projections follow the contours of the towers, windows and masonry relief. This layering creates a particularly effective impression of movement: the gate seems to crack apart, burst into flames or open onto another world, without any physical alteration being made to the monument.
Lú does not simply use a few Celtic images to create a Halloween atmosphere. The festival is rooted in an area deeply associated with Ireland’s ancient tales. Drogheda stands at the gateway to the Boyne Valley, home to major prehistoric and mythological sites including Newgrange, Knowth, Dowth and the Hill of Tlachtga.
This region is closely linked to Samhain, the festival that marked the transition to the dark season in the ancient Irish calendar. Tradition described this period as a time when boundaries became uncertain, and the human world and the Otherworld could draw closer together. This narrative material naturally suits a night-time festival built around appearance, metamorphosis and illusion.
The name “Lú” also refers to County Louth and evokes Lugh, a major figure in Irish mythology. This god of many talents belongs to the Tuatha Dé Danann and plays a prominent role in tales of the Mythological Cycle, notably during the Battle of Mag Tuired. The festival draws on this heritage without becoming a history lesson: legends are told through movement, colour and sound.
Lú is best approached as a night-time walk with several stops. Sequences are presented on different monuments, and visitors move freely through the town centre. There is therefore no single main stage in front of which to spend the entire evening. This format allows you to arrive when you wish, create your own route and watch a projection again if you particularly enjoyed it.
The 2026 programme also includes a wider range of cultural entertainment across Drogheda, with performances, music and the Spooks Parade. Unlike the outdoor projection trail, some additional events held indoors may be ticketed or require booking. Details of these activities may be added as the festival approaches.
The atmosphere is generally family-friendly at the beginning of the evening. The stories may feature unsettling creatures and Samhain imagery, but the light trail is not designed as a horror attraction. Children who are able to walk around a lively town centre can fully enjoy the colours, music and visual transformations of the buildings.
Bring warm, waterproof clothing: at the end of October, the weather can change quickly, and most of the trail takes place outdoors. Comfortable shoes are also recommended, as several of the older streets have cobbles or uneven surfaces.
For a smoother visit, arrive before the illuminations begin to locate the three main monuments in daylight. You can then follow the route as the light fades, without wasting time looking for the different stops. Families may prefer the start of the evening, which is generally less busy than peak periods.
The projections can be viewed from public spaces, although some areas may be temporarily managed to keep pedestrian traffic moving. Follow the instructions of the teams on site and avoid standing in the middle of a thoroughfare to take photographs. A recent smartphone is enough to capture a memento, provided you turn off the flash: it will not improve photographs of an illuminated facade and may disturb other visitors.
The festival is also an excellent opportunity to discover Drogheda beyond its illuminations. Before nightfall, you can explore West Street, visit the main monuments of the historic centre or extend your break in the Boyne Valley. Lú thus offers an original gateway to a town that is still too often passed through without being explored.
