[1] The church dates to the early 19th century and is a Grade II* listed building.

[2] The church at Tregaminion was established as a chapel of ease to St Andrew's in Tywardreath.

It was built at the sole expense of William Rashleigh of Menabilly, who also endowed the church with £50 a year for its upkeep.

Construction work was completed in 1815,[3] and the chapel opened for divine service on 1 October 1815.

It was made from polished white alabaster by Harry Hems of Exeter and includes the Rashleigh coat of arms.
