This Catholic church is a 20th century creation, built in 1933. The architect was Giuseppe Rinvolucri, an Italian from Piedmont who came to Wales after World War I, settled in Conwy and designed several Catholic churches in Wales and England. It is in a simplified Romanesque style, with Arts-and-Crafts influences. The nave and chancel are rectangular, tall and narrow, built of bare rubble stonework inside and out. The roof was originally concrete with a rounded interior ceiling but is now covered with a steep slate roof.
