The Dominican Priory is one of Tallaght’s best known buildings, and is situated in Tallaght Village. Almost seven hundred years ago, a castle stood here, which was built to defend the Pale from Irish invaders. Believe it or not, part of the castle, a tower, still stands and is part of the Priory building. The castle was replaced by a palace for the Archbishop of Dublin, and that, in turn, was replaced by a large mansion.
In 1855 the Dominican Order founded the Priory of St. Mary where it stands today, and it has served as a training college for priests of the order ever since. You can see a statue of St. Dominic, the founder of the order, in the grounds of the Priory.
