Overview
The monastery that once stood here produced two landmarks of early medieval Irish writing – the Martyrology of Óengus and the Stowe Missal – before Vikings sacked it in 811. What you see now is much later: a Victorian Dominican priory on Tallaght’s Main Street, built in Gothic Revival stone, with one genuinely medieval element folded in, the five-stage tower of Tallaght Castle. The site works as a parish church, a retreat centre, and the home of the Priory Institute, which teaches theology and philosophy by distance learning. It is not really a visitor attraction, and worth knowing that before you go: the best time to see inside is around a service.
A millennium of faith and learning
Saint Máel Ruain founded his monastery here in the third quarter of the 8th century, and it quickly became the leading house of the Céli Dé (‘Culdee’) reform. Tallaght produced some of Ireland’s most important early manuscripts, the Martyrology of Óengus and the Stowe Missal among them. The Viking raid of 811 ended its golden age, though it lingered as a rural bishopric until 1152.
After the Normans came, the site changed hands several times. In 1179 Saint Laurence O’Toole secured a papal grant moving Tallaght to the See of Dublin, and in 1324 Archbishop Alexander de Bykenore built a castle directly onto the old monastic ground. Its tower is the priory’s oldest surviving anchor.
The Dominican Friars arrived in 1855 and set up a novitiate. They laid the foundation stone for the priory buildings in May 1864 – Rev. Goodman, the Dominican provincial, did the honours – and the complex grew over the following century, with a connecting wing in 1903 and a library block in 1958. The Dominican Studium taught here from 1935 until 2000, when it moved to St Saviour’s in the city and the Priory Institute took over the teaching.
Architecture and grounds
The exterior is straightforward 19th-century institutional Gothic Revival: ashlar walls, pointed and flat-headed windows keeping their original timber sashes, carved bargeboards on the gabled dormers, and stone chimney stacks over a pitched slate roof. The plain Victorian masonry set against the blunt medieval tower is the thing to look at – a thousand years of building in a single glance.
The grounds hold more than the church. The Archbishop’s bathhouse survives, along with a tree-lined Friar’s Walk and the site of St Maelruan’s Well, reminders that this was a working ecclesiastical estate long before the Dominicans. Inside, the church keeps a quiet, plain atmosphere, with a later side chapel for private prayer. The retreat centre next door, a three-storey building over an arcaded basement, hosts workshops and small groups.
Masses and parish life
As a working parish, the timetable is the practical heart of a visit. Sunday Mass is at 8am, 10am, 12pm and 6pm, with a Saturday Vigil at 7.30pm and Mass in Polish on the first and third Sunday of the month at 4.30pm. Weekday Mass runs Monday to Friday at 8am, 10am and 1pm, with two on Saturday mornings at 8am and 10am. There is Adoration on Saturdays from 10.30am to noon, and Confessions on Saturday mornings and after the Vigil. Selected services are streamed on the parish website.
Beyond worship, the priory runs a St Vincent de Paul conference, St Catherine’s Counselling Service, and Rollebon Press, which prints liturgical and catechetical material sent around the country. The friars also publish Alive, a free monthly Catholic newspaper. The Priory Institute, meanwhile, offers blended-learning degrees in theology and philosophy, with Saturday study days at the priory, and enrols for the autumn each year.
