The original church was cruciform in plan but a tower was added (probably in the 13th century) and then the aisle. There are old wagon roofs and a funeral recess (14th century). The stained glass and some other ornamental work is the handiwork of the late 19th century vicar, William Willimott, and there are three brasses (1471 to Roger Kyngdon, and 1631 to Richard Chiverton, d. 1617, and his wife). The church was
restored in the 1880s after becoming virtually ruinous in the 1870s. Willimott's predecessor as vicar was the Rev Dr John Rooke Fletcher (d. 1878) who was vicar for 61 years. There were Methodist chapels and almshouses (Directory for 1873). There is a Cornish cross in the churchyard. An account of its discovery was published in the
Journal of the Royal Institution of Cornwall; vol. 7, 1882. Arthur Langdon said of it: "Undoubtedly this is a magnificent monument, and in regard to height is, with the exception of the cross in Mylor churchyard, since discovered, the tallest in Cornwall". The vicar of Quethiock is the Revd Margot Davies. ==References==
