The village gets its name from Saint Rhidian. Its church is dedicated to St Illtyd and St Rhidian. The present building was constructed in the 13th century, with a chancel and tower added in the 14th century. In the porch may be seen a 9th-century stone, bearing simple carvings of human figures and animals. A standing stone on the village green may be the remains of a village cross.
