The church at Cley is among my favourites. Here's a plc I took back in May:

St, Margaret's, Cley-next-the-Sea, from the graveyard of St, Mary's at Wiveton.

Plenty of hills in Norfolk; none of them to do with the Biblical flood, alas. It was people puzzling over finding seashells on high ground that helped inspire such mythology in the first place.
