St Erney Church was dedicated to St Terninus. The river Tidi separates it from the parishes of Sheviock and St Germans. St Erney was originally the mother Church of Landrake, although it has since become subordinate to Landrake. St Erney Church is said to have been built by the Dawneys of Trelugan and it dates from the 14th and 15th centuries.
A small church in an lonely setting with an unusually squat tower. St Terninus or St Torney is also the saint to which North Hill Church in the upper Lynher Valley is dedicated.
The font is thought to date from 1080.
The arcade consists of four four-centred arches of fine granite supported on monolith pillars of the same material. There are north and south doors, but no porch.
The tower is of two stages, finishing with battlements and stump pinnacles; it contains three bells.
