Our Lady of Lourdes Church was designed by the Birmingham ecclesiastical architect G. B. Cox in a free French Gothic style.

[1] It is constructed of reinforced concrete faced with white stone, with a platform and adjustable jacks in the crypts to mitigate subsidence from mining.

In the corner formed by the east transept and the chancel are a single-storey sacristy and a two-storey bell turret with pyramidal roof which contains the organ gallery, reached by a stone spiral staircase.

The grounds include a Lourdes grotto and were laid out with wide paths and terraces; annual diocesan pilgrimages began in 1966.

The site of the current church was purchased in 1923 after a fundraising campaign, in order to fulfill the dream of the late priest, Father Patrick Boyle, of creating a replica of the grotto at Lourdes to be a pilgrimage destination for those who could not travel to France.
