St Dingat's is located on the south side of James Street, New Tredegar, set back from the road. The church, comprising a chancel and single-aisled navel under a continuous ridge, was built in 1892-3 to designs of Seddon & Carter, the south aisle added by them in 1899. The north vestry and peculiarly profiled north bell gable is presumably a further addition by Carter.
The church is built of rock-faced Pennant sandstone and yellow terracotta. The spacious interior is designed in the Early English style, the five-bay arcades with circular piers and spurred capitals. The roofs are boarded, of trefoil profile in the nave, that in the chancel with concealed hammerbeams.
