it looks like the lovely BT building which I avert my eyes from every time I pass it. If it is then I guess you were standing close to the bridge to K college.
Perhaps Dover could showcase it's heritage with this building, Burlington House and the new bete noire the Gateway flats?
will have to accept your answer paul, i thought it was from st martin's battery but just come back from there and the views do not tally with the photo.
