Trewan Hall
Trewan Hall (pronounced Trew-an) is a historic manor house in the parish of St Columb Major, Cornwall, England, UK. The surviving Jacobean style manor house is located one mile north of the town.  It was the ancestral estate of the Vivian family (later Vyvyan, when a Vivian daughter married a distant cousin with varied spelling) for over 300 years, until it was sold in 1920.

The house and gardens, which now includes campsite grounds, has been privately owned by its current owners since 1960. Although the manor house is not generally open to the public, it holds annual open days as part of the National Gardens Scheme.

The Manor House
The existing main house dates from circa 1633, and was built by the Vivian family as a replacement for the former manor house at Trenoweth (now Higher Trenoweth Farm), a short distance from Trewan. The building is a Grade II* Listed structure. Its origins are in the 15th century, but most of the fabric dates from 1635 onwards (a fireplace is inscribed with this year). Further alterations were executed in the late 19th century including a number of Gothic Revival windows added in the perpendicular style.

The Campsite
The Campsite was founded in 1963 by Dennis and Phyllis Hill who purchased the estate in 1961. The campsite is still ran by the family and has developed to cater for 170 pitches spread over 36 acres of woodlands and fields. All developments have been made to be sympathetic with the historical buildings and grounds of the estate. The site includes a 25m heated swimming pool, several blocks of facilities, a playpark, a camp shop, and other amenities. In high season the barns open to local entertainment and there are various food options through the week. The site is open from mid May and mid September.

The Vivian family
Several generations of the Vivian family lived in nearby Trenoweth before the manor house was built in Trewan circa 1633. In 1697, only-child Mary Vivian, of Trewan Hall, St Columb Major, married her distant cousin Sir Richard Vyvyan, 3rd Baronet of Colan, Cornwall. This united two branches of the family which had been separated for three centuries, and continued the family line under the spelling Vyvyan.

Through the centuries, some members of the Vivian family have served in official capacities. At least two members served as Sheriff of Cornwall: John Vivian from 1680–1681 and Thomas Vyvyan in 1779. Vivian family Members of Parliament include: Thomas Vivian (1617–1691), Francis Vivian (1649–1690), and John Vivian (1647–1691).
