It is at Egeskov Castle in Denmark. Thanks Daniel Roth for including it on "sundial links" Roger Bailey ______________________________________________________________________ The Sundial "Helix Helios" is nine meters tall, and was given to Egeskov in 1989 by the multitalented Piet Hein. The time is shown on the twisting spiral.
