Saumarez Park
Guernsey's largest public park, with a rose garden, a Japanese garden and a folk museum.
Updated 18 October 2026
Saumarez Park at Castel is the island's largest public park, the grounds of the Saumarez family's manor, acquired by the States of Guernsey after the 4th Baron de Saumarez died in 1937, with a walled rose garden, a Japanese garden with a pond, mature specimen trees and lawns. The National Trust of Guernsey runs a folk and costume museum in the old farm buildings, and the Viaer Marchi, a traditional fair, is held in the park each summer.
History
The estate came to the Saumarez family through the 1788 marriage of the future Admiral James Saumarez, 1st Baron de Saumarez, to Martha Le Marchant. When the next heir put the property up for sale, the admiral's grandson James Saumarez (1843-1937) used his droit de retraite, the right of redemption, in 1869 to buy Saumarez Park and the nearby Le Guet estate; a diplomat who travelled widely, he created a set of exotic gardens, with a bamboo walk, a Japanese garden, a camellia lawn, a rose garden and a walled garden. After his death the States of Guernsey acquired the park; the manor house is now a residential care home, and the National Trust of Guernsey's Folk & Costume Museum occupies restored farm buildings near the Victorian walled garden (Wikipedia, Saumarez Park).
