The original foundation was the first church the Jesuits built in Wales after establishing St Beuno's College in 1848.

Afterwards the local Assembly Rooms in the town centre (which is now occupied by Jobcentre Plus) were rented to serve as a church and a school.

[1] On 3 March 1863, the foundation stone was laid by James Brown, Roman Catholic Bishop of Shrewsbury.

[3] At some point in the 20th century, the Jesuits handed over the administration of the church to the Diocese of Wrexham who continue to serve the parish.

[4] In 1955, the old school that was housed in the original parish chapel had to be moved, as the building was in a state of disrepair.
