[3] In 1707 permission was granted to John Holles, 1st Duke of Newcastle to enclose 3,000 acres (1,200 ha) of Sherwood Forest, and re-purpose it as a deer park.

[6] At his death in 1768, his nephew Henry Fiennes Pelham-Clinton inherited the title and the estate, and made Clumber Park his residence.

[citation needed] Henry Pelham-Clinton, 7th Duke of Newcastle, was a minor at the time of the fire and the trustees approved the new plans by Charles Barry in 1880.

[14] Another fire, in 1912, caused less damage, but the effects of the First World War and the Great Depression forced the abandonment of the mansion, which, like many other houses during this period, was demolished in 1938 to avoid a tax bill.

[citation needed] The Duke's study, designed by Barry, is all that survives of the main house and is presently home to the Clumber Café.

[18] Clumber Park is over 3,800 acres (1,500 ha; 5.9 sq mi) in extent, including woods, open heath and rolling farmland.

[20] The 4-acre (1.6 ha) walled kitchen garden east of the cricket pitch has a glasshouse 450 ft (140 m) long and containing Pelargoniums, grapevines and a Butia capitata palm.

A floating pontoon platform to support scaffolding was built and stonemasons started to rebuild the bridge using some original fragments in October 2019.

[29][30] Just over a week after the bridge damage, a waste-bin, a National Trust van and a barn known as The Bunk House were set alight in an arson attack.

[32][33] Starting from 2009, a grant of £797,000 from the Heritage Lottery Fund enabled renovation of the Grade II listed derelict old brewhouse, part of the old stable block, to create an exhibition and discovery centre.

A wide variety of species-rich habitats surround the former mansion, including the lake and wetlands, grassland, heath and mature deciduous woodland.

There are breeding birds of woods and heath including nightjar, woodlark, redstart, hawfinch, water rail and gadwall ducks.

In January 2018 the National Trust sent a "heartfelt letter" to the environment manager at fracking company Ineos, asking her to visit the park and to stop its survey there for shale gas reserves.

[38] Close to the main parking area is a cricket pitch with a thatched roof pavilion in the style of a cottage, clad in rustic split logs.
