A large neo-Romanesque church designed by the architect-priest Fr Benedict Williamson (1868-1948), its interior is both austere and serene. Greyfriars is the only flint-stone building in the city, and its green spire is a local landmark. The external stone dressings are Derbyshire grit stone and the roof tiles are red Bridgwater tiles.
The foundation stone was blessed on 17 September 1910. In 1954, the porch on the liturgical North side was bricked up with flintwork and a plaque of Our Lady and the Angels installed. The porch was converted into the present chapel with the Spanish painting by Bernardo Germán de Llórente (1685 – 1757). The (hitherto disused) West door was reopened and an inner timber porch built. The same year, a new organ was installed and benches designed by a parishioner replaced the original chairs.
