It is situated to the north of the centre of Croydon on the junction of Wellesley Road and Station Road, next to St Mary's Roman Catholic High School, Croydon, but its parish extends to the west of the town.

The church was also given a £2,000 donation for its construction by a Lady Elizabeth Lloyd Anstruther of Ryde.

She was the granddaughter of Peter Burrell, 1st Baron Gwydyr, and niece of John FitzGibbon, 2nd Earl of Clare.Her aunt, Countess Elizabeth Burrell (1793–1879), funded many of the Catholic churches on the Isle of Wight and in the then Diocese of Southwark after meeting and being friends with Thomas Grant, the first bishop of Southwark.

Elizabeth Lloyd Anstruther, after donating the money for the church's construction, would, a few years later, become a Benedictine nun in St Mary's Abbey, Colwich.

He extended the chancel by adding side chapels, as well as north and south aisles to the church and the sacristy was enlarged.

So in 1972, the front entrance to the church was extended, a parish hall added and a new presbytery built.
