John, What do you think of the dial in France at Mont St. Michel? The top of the cathedral on top of an island is the endpoint of the gnomon for a dial on the beach. It only works at the equinoxes, but still is a sundial. I don't know if it still exist. More information has circulated on the list but I don't have it anymore.
