The church at St Athan was erected in the 13th century, probably on the site of an early-medieval temple from the sixth century. Its founder may have been Philip de Nerber from Castleton. Significant extension and reconstruction of the church was made in the fourteenth century (transept) and in the fifteenth century (porch, upper part of the tower). In 1888 a thorough renovation of the building was carried out, unfortunately, medieval wall polychromes were than destroyed.
The church was erected in the English decorated gothic style, on a cruciform plan, consisting of a rectangular nave, southern and northern transepts, rectangular chancel on the east side and a tower located at the intersection of naves. In addition, the southern entrance to the nave is preceded by a porch. Inside the church there are wonderful 14th-century tombstones of Sir William Berkerolles and his wife Phelice de Vere and Sir Roger Berkerolles and his wife Catherine Turberville de Coity.
