The foundation stone of St. Mary's church (which was intended to replace St. Hilary's) was laid on 6 July 1871. The consecration service was due to take place on 29 January 1874; but on 27 January 1874, the Bishop of St. Asaph announced that he would not conduct the ceremony, because he considered that a panel of the reredos "had a somewhat ritualistic tendency". Eventually the panel was removed, and after a delay of almost two years, the Bishop consecrated the church on Tuesday, 7 December 1875. There were further interruptions during the consecration service.
St. Mary's now serves, to all intents and purposes, as the parish church of Denbigh.
