Donovan held services in the rooms of local houses until a small church was erected on Park Road.

This was opened on 11 September 1891, on the very day that the steeple of the nearby St John's Church fell down.

He worked to have a new, larger, church built to accommodate the increasing size of the local congregation.

The inscription on the foundation-stone, translated from Latin reads: On 1 September 1939, it was reported in the Catholic Herald that the church celebrated the 31st anniversary of its consecration.

St David's church was built in 1814 as a Seion Wesleyan Methodist chapel, re-built in 1872 and was purchased and converted for Catholic use in 1998.
