The parish church is dedicated to Saint
Sidwell and Saint Gulval or to St
Michael. The inclusion of St Gulval in the dedication is apparently due to a mistake by Dr.
Oliver who understood entries referring to the church of "St Wolvela of Lanestly" as referring to Laneast whereas "Lanestly" is the old name of
Gulval. The church and cemetery were dedicated in 1436; before that time burials were made at the mother church of
St Stephen's. Parish land was divided between the hundreds of
Lesnewth and
East Wivelshire, the church being in the latter. It was founded and maintained by the Augustinian canons of St Stephen's; thereafter it became a donative served by perpetual curates. In the churchyard is a four-holed Cornish cross which was found in 1952 buried in the churchyard. The lower part of the shaft and the base were made in 1954. , the astronomer who discovered the planet
Neptune. There is a Cornish cross on Laneast Down. It is unusual in being made of
Polyphant stone rather than granite; the two sides of the head are elliptical and have Latin crosses. ==Lidcott Mine==
