Overview
Lusk’s round tower has nine floors, more than any other round tower in Ireland, and it went up for a reason: raiders were coming in off the coast in the 9th century, and the tower gave the monastery a bell-house and a bolt-hole in one. It still marks the village out from a distance. Lusk sits about 20 km north of Dublin and has grown into a commuter town, but the medieval core around St MacCuilinn’s is nationally significant and worth the turn off the M1. The name comes from the Irish lusca, a cave or underground chamber: Saint MacCuilinn, who founded a church here around 450 AD, is said to have lived in, or been buried in, a cave on the site.
If you have twenty minutes, spend them in the churchyard. The round tower, the 15th-century belfry and the carved tombs all sit in one compact enclosure, and it costs nothing.
History and heritage
People have been here a long time. Archaeologists working the surrounding fields have turned up Bronze Age cooking pits. By the 5th century Saint MacCuilinn had founded a monastery that grew into a regional religious centre, and its wealth is what drew the Vikings in the 9th century. The round tower was the answer. It stood around 32 metres to begin with and reaches about 27 metres now, with nine floors – the most of any surviving Irish round tower.
Anglo-Norman rule later added a 15th-century defensive tower to the enclosure. The adjoining belfry now shelters the best of the site’s carved stone: a 17th-century font, a ballaun stone, a fireplace with a carved Annunciation, and several medieval tombs, chief among them the double effigy of Sir Christopher Barnewall and his wife Marion Sharle. Look up for a carved ‘grotesque’ figure, decorative rather than a working gargoyle. The antiquarian Austin Cooper once recorded a sheela-na-gig here; it hasn’t survived. Older lore reaches back further again, tying the district’s early name, Bregia, to Emer, wife of the Ulster hero Cú Chulainn.
What to see and do
The round tower and belfry
The tower is a state-owned National Monument in the care of the Office of Public Works, and here is the honest bit: you can’t normally climb it. This isn’t a site you turn up to and ascend. Getting into the medieval belfry, where the tombs and font are kept, has traditionally meant borrowing a key held locally – ask at Kelly’s garage rather than assuming a door will be open. Plan around the churchyard and the exterior, and treat any glimpse of the interior as a bonus.
Lusk Heritage Centre
Housed in the St MacCuilinn’s church complex, the heritage centre is free and sets the context for everything around it. Its exhibition follows how churches across Fingal developed and includes reproductions of the Barnewall tomb. A well-kept thatched cottage at the entrance to the village is a quick primer in traditional rural building before you reach the enclosure.
Food, drink and festival
For its size, Lusk grows and makes a surprising amount. Lusca, an offshoot of Llewellyns Orchard, is one of the very few Irish producers making wine from grapes grown here rather than shipped in. The market-garden country around the village supplies fruit and vegetable growers along the east coast.
The Man O’ War, out on the old Dublin road, has deeds going back to 1595 and started life as a turnpike toll booth before it ever poured a pint. The village keeps a pipe-band tradition alive through the Black Raven Pipe Band. Time a summer visit for the Lusk Summer Festival, which takes over Orlynn Park each June (21 June in 2026) with music, a market, food stalls and free workshops.
Nature and wildlife
A short walk from the centre brings you to Rogerstown Estuary, a former landfill reclaimed as a nature reserve. In winter its tidal flats draw waders and wildfowl, and a coastal walkway linking Dublin to County Meath is being developed along this stretch. The paths here are flat and buggy-friendly – a gentle hour rather than a proper hike.
Practical information
- Round tower access: Climbing the tower isn’t generally possible, and there’s no reliable schedule of guided climbs, so don’t build a day around one. Access to the belfry has depended on a key held locally (ask at Kelly’s garage).
- Admission: Free.
- Getting there: Lusk is served by Rush and Lusk station on the northern commuter line – not the DART, despite what you’ll sometimes read; a DART extension to Drogheda is only proposed. Buses also serve the village. Drivers come off the M1.
- Parking: Free on-street parking near the heritage centre and round tower, though it fills fast on festival days. Round Towers Service Station allows up to four hours’ free parking for cars, and there’s a car park at Rush and Lusk station.
- Accessibility: The heritage centre is wheelchair-friendly. The belfry and tower involve narrow, uneven stone steps and aren’t suitable for wheelchair users or anyone with limited mobility.
Nearby attractions
Lusk makes a decent base for the north coast. A short drive north brings you to Balbriggan, with its long sandy strand and historic harbour. West lies Balrothery, with quiet paths and the ruins of Balrothery Castle for a second helping of medieval history. Pair either with the churchyard and you have a half-day that covers archaeology, coast and a bit of local character without much time in the car.
Come for the June festival or a dry winter weekend on the estuary, and don’t count on getting inside the tower – the belfry and the carved tombs are the real reason to stop.
