Many a church guide claims that their present building sits on the site of a more ancient structure. But how accurate are these claims? Recently the Fishergate, Fulford, and Heslington Local History Society (FFH) – a community group with a long-standing and very active interest in their historic landscape – decided to try to find out whether this was true of the deconsecrated medieval church, dedicated to St Oswald, that sits on the east bank of the River Ouse, in the village of Fulford, some 2km south of York.
