Plans, drawings, photographs (negatives, with prints and lantern slides of a selection), and documentary material concerning repairs and alterations to Durham Castle. Structural reports on Durham castle in 1925 and 1927 drew attention to its state of advanced disrepair, and the likelihood that parts of the building would eventually slide into the river unless urgent measures were taken to stabilise the foundations. The contents of this collection relate primarily to the extensive programme of repairs carried out between 1924 and 1939, and to the appeal launched by the Durham Castle Preservation Fund to raise the necessary resources.
The documentary material includes reports on the structural state of the castle, correspondence between architect and contractors, estimates of costs, accounts of expenditure, appeal committee minutes, correspondence, publicity and press cuttings. The negatives (over 500) provide a detailed visual record of the main programme of work between 1929 and 1938, with more selective coverage of earlier work in the 1920's. The plans and drawings number almost 700. The architects for the project were W.T. Jones F.R.I.B.A., until his death in 1932, and later Sir Charles Peers. The consulting engineer was Dr. Oscar Faber. The Clerk of Works, C.A. Linge, was also the photographer for the main phase of work from 1930 onwards, and compiled a detailed inventory of photographic work undertaken. Most of the earlier negatives appear to have been taken by Edis, the leading Durham firm of photographers. The main contractors were John Thompson and Sons, Peterborough, and the borings were done by Andrew D. Brydon Ltd of Harrogate.
The collection also includes one volume and a photograph of a drawing relating to proposals for work on the Norman Chapel, etc., 1951 (CAS/B19 and P41, architects Seely & Paget, contractors George Gradon & Son, Ltd), and two earlier drawings ca.1885 and 1919 (CAS/P40 and 42) of the Tunstall Chapel and castle kitchen respectively.
