(In the distance there is an old tower. This looks to me like one of the prettier french water towers. Magny Cours has a 'Chateau d'Eau' corner, but the photos I've seen from Grand Prix days show something far more utilitarian. But still grander than the sombre metal structure we had at Silverstone, just outside Abbey.

Do you mean the tower with the conical top (top right, on horizon)?
There is still a structure of that shape a way from the southern end of the circuit. But I didn't think that was the water tower? The thing I *thought* was the tower when I've been there was a lower, dumpier looking circular thing with a flat (open?) top and a ring of narrow brick arches around its base; but that was just my assumption, and I don't recall it being visible from the track.
Whatever, your eagle-eyed spot lends credence to it being at Magny Cours.
EDIT:
I guess my 'assumption' was wrong - there is a taller pointy-top structure, as per the picture, still extant on Google Earth view, which looks plausibly like a water amenity, due East of the grandstand overlooking the eponymous corner (oh, and it is sited on a 'Rue de Chateau d'Eau' too...). Having said that, the smaller, and quite possibly older, structure I had in mind is very much closer to the circuit - just outside the site boundary near Chateau d'Eau corner - so who knows which it was named after?
