The parish church at 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 by Edmund Lacy, Bishop of Exeter in 1436; before that time burials were made at the mother church of St Stephen's. The land of the parish was divided between the hundreds of Lesnewth and East Wivelshire, the church being in the latter. It was founded and until the Reformation maintained by the Augustinian canons of St Stephen's; thereafter it became a donative served by perpetual curates.
