The church of St. James in Rudry was erected in the middle of the 13th century, perhaps in 1254. The first written record of it comes from 1295. For most of its history, it was a chapel of ease of St. Barrwg’s church in Bedwas, separating only at the beginning of the 20th century. A thorough renovation of the building was carried out in 1885, and then in 1961, the walls of the nave and tower were reinforced and the roof tiles were replaced. In the 19th century, before the southern entrance to the nave, a porch was placed.
The medieval church consisted of a rectangular nave, a narrower and lower, short chancel on the eastern side and a four-sided tower on the western side. The tower is covered with a hip roof, characteristic of these areas. Most of the windows have been modernized, except for the two-light opening from the 16th century in the northern wall of the nave, topped with the so-called ogee arches.
