Ruin. Remains of Ravensworth Castle. By John Nash 1808, for Sir Thomas Liddell (1775-1855), industrialist and politician, 6th Baronet, and son of Sir Henry George Liddell (1749-1791). In 1821 he was made 1st Lord Ravensworth. With his wife Maria Susannah Simpson, he had 12 children. In 1807 he retired from politics to concentrate on mining and building a new house. His friend the Prince of Wales (George IV) recommended John Nash to design the country house. The RIBA archive holds over 50 drawings of Nash's house. The west end is more reigorously Gothic Revival and may have been inclufenced by A C Pugin who worked with Nash. Changes were made after Nash's death in 1835. The principal elevation was attributed to Sir Thomas when it was finished in 1846. Parts of the house were useable by the late 1820s. Grand weekend parties were held, such as one in 1827 for the Duke of Wellington and another for Sir Walter Scott, novelist and poet, who noted that the house was 'but half complete'.
Ashlar sandstone; Castle style. 4 storeys with door opening at ground floor, 2-light window opening under label moulds at first and second floor. Ruined third floor window opening. Historical note: some building work designed Sir Thomas' son Thomas Henry Liddell, about 1822. Building completed 1846. James Paine carried out alterations to the castle {1}. The medieval (the north and south towers and sections of curtain wall remain) and post medieval castle buildings were demolished to make way for the gothic-style country house. During the First World War the 6th battalion of the Durham Light Infantry trained at Ravensworth. In the 1920s and 30s the house was a residential girl's school. The Liddell family had moved to Eslington Park in Northumberland. The school closed in 1932. In the 1930s coal was extracted from beneath the house which left it unstable and subsiding. By the Second World War the castle had been abandoned and was being dismantled. Stone from the castle was used to build a model village. What was left of the castle was demolished in 1953, leaving the medieval towers, cellars and stables. The surviving buildings were listed in 1959 and in 1977 the medieval towers and original castle curtilage (HER 106) were scheduled.The surviving above-ground elements of the Nash house are the octagonal tower with dressing room turret and parts of the servants wing attached, cellars beneath and the remains of part of the kitchen range some distance to the east. The rest of the house is largely represented by piles of demolition debris and some stone footings. During consolidation works in 2014 a short dog-leg passageway was noted at first floor level which is not visible from the ground. These were photographed for the first time from a cherry picker. The fragmentary remains of the Nash House still reflect something of the granduer of the original building and are of exceptional evidential and historic value. The remains of the house and stables represent what survives of the largest Gothic Revival country house in the north-east and a prime example of work by John Nash.
