Trevalga (Cornish: Trevelgi) is a coastal civil parish and hamlet in north Cornwall, England, United Kingdom.

Dating from the time of the Domesday Book (1086), the hamlet of Trevalga lies 500 metres (1,600 ft) from the coast on the seaward side of the road from Boscastle to Tintagel.

Unusually, much of the hamlet (The Manor of Trevalga) was, from 1961 to 2023, part of an estate held by The Gerald Curgenven Will Trust with profits after maintenance going to Marlborough College, a public school in Wiltshire.

Upon his death in 1959, at his bequest the estate was placed in a trust to preserve The Manor of Trevalga, with post maintenance profits from rent benefitting his old school, Marlborough College.

In October 2023, it was reported that the Manor had been sold for £16 million to Castle Lane Securities, a subsidiary of the British property company William Pears Group.

In Gerald Curgenven's will (died 1959) he established a charitable trust which protects Trevalga, instructing that the village be managed as it was during his lifetime, while providing yearly donations to his old school Marlborough College.

[citation needed] It is understood locally that the school initially tried to claim Trevalga directly, but this failed and the trust was officially formed in 1961.

[13] Thereafter, protests and petitions were set up, using the social networking website Facebook in an attempt to prevent the sale[14] which received national attention.

The legality of the sale was disputed by the residents of the estate who secured the opinion of Edward "Ted" Nugee QC, on an informal and fee free basis.

[citation needed] In 2020, residents secured a further legal opinion which established that preservation of the Manor was part of the charitable purposes of the trust, and therefore not to be sold.

[citation needed] On 23 June 2022, in the midst of Cornwall's ongoing housing crisis,[16] the trustees of the Gerald Curgenven Will Trust wrote to tenants to inform them they are selling Trevalga.
