is it Lancing School?
very fine looking place, whatever school it is
You are correct, it is Lancing College.
And no, technically, I never attended there, though Flushy may well have done, (it costs £27,000 per year) & it is in Flushy-Shire.
Incredible building, with the added plus of being so beatifully set on a hill, overlooking all around, & perfect scale.
Someone told me that scenes for the Henry Potter films weere filmed there, but I don't know if that is so.
Some interesting scholars there down the years, too.
The last photo of it that Post I uploaded earlier was taken from the aeroplane I was in. By me. As was the Arundel Castle photo.
