In 1992 I visited a chateau near Cherbourg in France (Crosville sur Douvre I think it was, but I'll check on that when I get back from school).
On one of the windowsills there was a sundial scratched into the horizontal surface, not accurate enough to be classified as a proper sundial but more than a scratch dial. It was a semicircle of diameter between 10 and 15 cm from what I remember. I'll sort out exact details later this evening.
I have never seen a similar dial, and wonder if this is of the type described.
