The church is the supposed resting place of St. Tewdric; on the north wall of the chancel is a tablet installed in the 17th century by Francis Godwin, Bishop of Llandaff 1601-1617, who claimed to have found the saint's stone coffin while repairing the church.

An earlier building was rebuilt as a private residence by Francis Godwin, Bishop of Llandaff, in about 1609/10, and much of the building remains from that period.
