As if that wasn't enough, there are two analemmatic sundials nearby. In this one, your own body becomes the gnomon casting the shadow. The smaller vertical stones represent the hours of the day, and the flat concrete date scale is the base on which you stand - in slightly different positions depending on the month of the year. The plaque on the taller post provides the instructions..
The Keppel Henge and the sundial are a project of both the Keppel Croft gardeners and a neighbour. You can find a lot more interesting details on the garden's website. All in all a very fascinating place!
