What it is
St Mary’s Abbey survives as two rooms below the modern street, and that is the whole visit. The great church and cloisters that once made this the wealthiest Cistercian house in Ireland are gone; what remains, down a short flight of steps off Capel Street on Meetinghouse Lane, is the Chapter House and the passage beside it called the Slype. The Chapter House is the reason to come: it holds the earliest rib-vault of any Cistercian abbey in Ireland, built around 1200, and it is where, in 1534, Silken Thomas Fitzgerald flung down his sword of state and declared himself in revolt against Henry VIII. That single afternoon is the site’s claim on Irish history.
One thing to know before you go: you can only get in on a guided tour. There is no drop-in, no self-guided route. The tours run seasonally, so check the Heritage Ireland website for current times before you set out.
A wealthy liberty
The monastery began in 846 as a Benedictine foundation, passed to the Congregation of Savigny in 1139, and joined the Cistercian Order in 1147. Sitting on the north bank of the River Liffey, the monks had direct access to Dublin’s markets and ran estates from Oxmanstown to the coast, which made St Mary’s the richest Cistercian house in the country.
That wealth bought power. The Chapter House regularly hosted the king’s council, and the abbey held a ‘liberty’, a charter that put it outside the city’s jurisdiction and let the monks run mills, take tolls, and claim goods from shipwrecks. It was not trouble-free: a fire in 1303 gutted much of the church, and in 1316 the mayor of Dublin briefly besieged the place, suspecting the visiting Earl of Ulster of harbouring Edward Bruce. The Reformation and Silken Thomas’s rebellion finished it, and the buildings were quarried and buried as the city grew over them. The remains were rediscovered in the 1880s, found about seven feet down beneath a bakery by an amateur archaeologist, and the site was made a National Monument in 1941.
What you see
- The Chapter House. The four-bay vaulted chamber is the centrepiece, its ribbed sandstone arches the oldest of their kind in Ireland. This was the second most important room in any monastery after the church, where the monks met each morning after Mass. The 13th-century statue of Our Lady of Dublin once venerated here now stands in the Carmelite church on Whitefriar Street, placed there in 1835 after it was rescued from use as a pig trough.
- The Slype. This narrow covered passage linked the cloister to the open ground to the east, where the infirmary usually stood. It now holds cases of pottery, floor tiles and other finds from the site and from Cistercian houses across Ireland, with panels showing how the vanished complex was laid out.
- The tour. OPW guides lead the hour-long tours, and the guide, Ralph, comes in for repeated praise in visitor reviews for bringing the abbey’s history and the Silken Thomas story to life. Trinity College paid almost €250,000 in 2014 for a manuscript made at the abbey in 1304, a measure of what was once produced here.
The 2023 dig for a hotel on the site turned up the remains of more than 100 people dating to the early 11th century, a reminder of how much of medieval Dublin still lies under these streets.

Visiting tips
- Around 16 June the Chapter House hosts free tours for the Bloomsday Festival, tied to its mention in Joyce’s Ulysses, which is the liveliest time to catch it.
- Take the tour rather than trying to read the room cold; the vault and the artefacts mean little without the context a guide gives them.
- Combine it with a wander through the medieval lanes towards Smithfield, which sits within the same historic quarter.
