The castle
Swords Castle was never a castle in the fighting sense. Archbishop John Comyn built it around 1200 as a residence and administrative centre for the Church’s wealthy Dublin estates, and what survives is a pentagonal ring of wall enclosing roughly half a hectare – a courtyard, a large chapel and a tower rather than a keep. Entry is free, it sits ten kilometres north of the city, and on a quiet weekday you can have the courtyard largely to yourself.
If you only have twenty minutes, spend them in the chapel. It is one of the largest surviving archbishop’s chapels in Ireland, and the restored roof, replica floor tiles copied from excavated originals, carved timber heads and stained glass give a clearer sense of the place’s original grandeur than any of the outer walls do.
History and archaeology
Swords was a religious centre long before the Normans. A monastic settlement traditionally linked to St Colmcille grew up along the Ward River from around the 6th century. When Comyn made Swords his chief residence shortly after 1192, he laid out a pentagonal enclosure of about half a hectare behind a curtain wall roughly 305 metres round – large for an Irish castle, and a mark of status rather than defence.
The fortunes of the place slid over the following centuries. By the early 1300s the archbishopric had moved on, and an inquisition in 1326 found the buildings in disrepair, probably after Edward Bruce’s campaign of 1317. Constables held the north tower from the 14th to the 16th centuries, and the Barnewall family kept the tenancy into the late 1500s. During the 1641 Rebellion the castle was used as a rendezvous for the Anglo-Irish Catholic families of the Pale.
The digging has kept turning things up. A 1971 excavation found a silver denier tournois of Philip IV of France in the chapel’s north wall; Philip reigned from 1285, which points to the chapel going up in the early 1300s rather than with the rest of the castle a century earlier. Stabilisation work at the gatehouse in 2014 revealed a sunken structure and human burials beneath it – a reminder that the open lawn sits on top of a lot of unexcavated history. The chapel itself was restored from 1995, and Constable’s Tower rebuilt between 1996 and 1998.
What to see
The grounds are laid out for self-guided visits, with signage at each feature:
- The chapel – the highlight, described above. It has long been a favourite for civil weddings, though bookings are paused at present while public works are planned.
- Constable’s Tower – rebuilt in the late 1990s, this three-storey tower has oak-floored rooms, a medieval garderobe and panels on the daily grind of the castle’s keepers.
- Gatehouse and curtain wall – the thick stone portal was the original way in; the wall running from it encloses the whole courtyard, with perimeter towers looking out over the Ward River valley. This is where the 2014 burials came to light.
- Knights and Squires block – a reconstructed three-storey building that once held the constable, a bakehouse, a stable and a carpenter’s workshop, showing how living and working quarters were stacked together.
- Courtyard and Town Park – the grassy courtyard connects straight into Swords Town Park, which has tennis courts, playgrounds and riverside paths if you want a longer walk.
Events at the castle
The grounds double as a community space. A Christmas Market runs in late November and early December, the Explore Fingal Market takes over on Saturdays from May to September, and summer brings family fun days with historical re-enactments. Informal trad sessions sometimes fill the courtyard in the colder months.

For a contrast, Ardgillan Castle sits further north up the coast, an 18th-century house with walled gardens and sea views.
