Barnard Castle School (colloquially Barney School or locally the County School) is a co-educational private day and boarding school in the market town of Barnard Castle, County Durham, in the North East of England. It is a member of The Headmasters' and Headmistresses' Conference (HMC). It was founded in 1883 with funding from a 13th-century endowment of John I de Balliol and the bequest of the local industrialist Benjamin Flounders. The ambition was to create a school of the quality of the ancient public schools at a more reasonable cost, whilst accepting pupils regardless of their faith. Originally the North Eastern County School, the name was changed in 1924, but is still generally known locally as the "County School". The school is set in its own grounds in Teesdale, within the North Pennines, an Area of Outstanding Natural Beauty. An on-site prep school caters for pupils aged 4 to 11, while the senior school caters for pupils aged 11 to 18. The school was previously funded by direct grant. Founded as an all-boys school, it has been fully co-educational since 1993. There are around 660 pupils and some 200 members of staff. Since the 1980s, the school has been one of Britain's most successful at producing top class rugby union players. During this period it schooled England international players Rob Andrew and Tony and Rory Underwood. The school has also produced Mathew Tait, Lee Dickson and Tim Visser, and appeared in three finals of the inter-school Daily Mail Cup. Former pupils in other fields include Edward Mellanby (the discoverer of Vitamin D); industrialist Percy Mills, The Lord Mills; fashion designer Giles Deacon and poet Craig Raine. History The school can trace its origins to an endowment made by John I de Balliol, then Lord of Barnard Castle, in 1229. The school itself was established in 1883 when it occupied temporary premises in Middleton One Row, County Durham, whilst construction of the school was undertaken in Barnard Castle. Initially there were 25 boarders and 10-day pupils, but by the end of 1884, there were 76 boarders. Originally known as the North Eastern County School, the main school building was completed on 2 February 1886 and initially housed 116 boarders and 12-day pupils. The Bishop of Durham presided over the foundation ceremony. The building was designed by Clark & Moscrop of Darlington in the Jacobean style, and is a Grade II listed
