Parts date back to the late 15th century and the church has a chancel, nave, north and south aisles and three-stage battlemented tower with nine bells.

[4] Lanhydrock estate belonged to the Augustinian priory of St Petroc at Bodmin but the Dissolution of the Monasteries during the 1530s saw it pass into private hands.

In 1620 wealthy merchant Sir Richard Robartes, of Truro, acquired the estate and began building Lanhydrock House, designed to a four-sided layout around a central courtyard and constructed of grey granite.

A barbican gate was added and the house was garrisoned by Parliamentary forces in August 1644 when Sir Richard Grenville, 1st Baronet took possession.

On the death of his mother in 1822, her surviving middle son Thomas Agar took up residence at Lanhydrock and adopted the Robartes name by royal warrant.

[5] Of the main house only the north wing, with its 116 feet (35 m) Long Gallery, and the front porch building survived intact, along with the original gatehouse, which dates from the mid-17th century.

The Robartes family suffered great losses during the First World War, including the heir Thomas Agar-Robartes, who was killed during the Battle of Loos in France, while trying to rescue a colleague from no-man's land.

[14] In 1934, to manage income taxes and death duties, the entire Cornish landholdings of the Agar-Robartes family were incorporated into the Lanhydrock Estate Company.

In 1953, faced with crippling death duties through a lack of his own children, the 7th Viscount Clifden gave the house and approximately 160 hectares (400 acres) of parkland to the National Trust.

Lord Clifden died in December 1974, and in a similar death duty exchange with HM Revenue, added 298 acres during the 1970s to the National Trust's estate holdings.

[15] He had married Patience Mary Basset in 1920 but died without male issue, and upon his death all his titles, with the exception of the barony of Mendip (which the 6th Earl of Normanton succeeded) became extinct.

[17] Lanhydrock was the main setting for a 1996 film version of Twelfth Night directed by Trevor Nunn, and starring Helena Bonham Carter as Olivia.
