Deene Park, the seat of the Brudenell family since 1514, is a country manor located 5 miles north-east of Corby in the county of Northamptonshire, England. Seven of the Brudenell family were Earls of Cardigan — the most notable being the 7th Earl who led the Charge of the Light Brigade at the Battle of Balaclava (1854). The 7th Earl died childless in 1868, and while the Earldom of Cardigan merged with the Marquessate of Ailesbury, the Deene Park estate passed to a collateral branch of the Brudenell family. The estate was inherited by its current owner, Robert Brudenell, in 2014; he is the son of Edmund and Marian Brudenell, who devoted their lives to the rehabilitation of Deene Park and are largely responsible for the estate's present appearance.
The manor of Deene belonged to Westminster Abbey; annual rent of £18 was paid until 1970. The manor house has been expanded around its courtyard from its sixteenth-century core, represented by its great hall, which was given its screen panelling and fireplace in 1571. The early 19th-century Bow Room contains the Brudenell library, collected in the 16th century by Sir Thomas Tresham and his son-in-law, Sir Thomas Brudenell, 1st Earl of Cardigan, though the collection no longer includes the manuscript of Chaucer's Canterbury Tales or the last copy of Magna Carta in private hands.
The house contains furnishings of different periods and portraits, including works by Joshua Reynolds and Thomas Gainsborough. Relics of the Crimean War include the uniforms of Lord Cardigan and the head and tail of his charger, Ronald.
The manor is located in the countryside not far from the Harringworth Viaduct and is surrounded by historic villages and hamlets. St Peter's Church, Deene, in the grounds, has the funeral monuments of the Brudenells.
