Scotland, Lochaber area; the Glenfinnan Viaduct. Built between 1897 and 1901. Glenfinnan Viaduct has been used as a location in several films, most famously Harry Potter and the Chamber of Secrets in which a substantial sequence revolves around the Hogwarts Express crossing the viaduct. Its appearances in two subsequent Harry Potter films, The Prisoner of Azkaban and The Goblet of Fire, has cemented the association of the viaduct with the film series. (panorama)
