The cjurch of St Mathias is located on the north side of Cardiff Road (B4254) at its junction with The Park. It was built in Early English style in 1895-6 to the (reduced) designs of architect J.L.Pearson of London. It is constructed of snecked, hammer-dressed Pennant sandstone with Bath stone dressings. The church comprises continuous nave and chancel and full-length north aisle, the south aisle planned but omitted after building had started. Internally, nave and chancel are defined only by a timber screen and by a change in the arcade design. Stained glass is by three different designers including R.J.Newbery.
