The site of Deddington Castle lies to the east of the town and comprises some 8 acres. At the present time it is a grassed-in enclosure surrounded by banks and trees on three sides, and is used as a recreational area for walking dogs and so on. There have been two recent archaeological "digs", one in 1947 and one in 1977. These have uncovered evidence of some Saxon building on the site, but the main evidence, both archaeological and documentary, is of the castle in the eleventh to fourteenth centuries. There was an inner bailey containing a stone hall, a solar and chapel, with a tower on the east side and a gatehouse on the west side giving access to the large outer bailey. Pottery from the 11th to 13th centuries was found on the site.
The site has been excavated twice: between 1947-1953 and again in 1977. The latter was carried out by Queens University Belfast (see pic above) and a very full account of the history of the castle, written by Richard Ivens, was subsequently published as an article in Oxoniensia 49 (1984), pp. 101–19. It is reproduced here (download in pdf format) with grateful thanks to the Editor and Committee of the Oxford Architectural and Historical Society.
