It was located at the corner of Nicholas St. and Christchurch Place, where part of its entrance may be seen next to the Peace Park.

It received its name during the episcopate of Alexander de Bicknor (1317–1349), when the parish of St. Nicholas was extended outside the city so as to include the Manor of St. Sepulchre and the Deanery of St Patrick.

It was established in St. Nicholas Within in the chapel of St. Mary and was under the authority of the Provincial of the Augustinian Friars of England.

During the Interregnum (1650s), Daniel Hutchinson, Thomas Hooke, John Preston and Richard Tighe, all served as alderman, were all Mayors of Dublin, and all worshipped at Dr Samuel Winter's independent congregation meeting at the Church of St. Nicholas Within.
