Multiple sundial at Culzean Castle

This multiple sundial in the walled garden was fantastic. It looks like the gnomon in the middle picture is probably angled at the latitude angle usually used for the slope of a horizontally anchored gnomon. Technically they should all show the same time so it is easy to assess the relative accuracy. They come with very variable precisions. Notice how the width of each scale division decreases in the middle photograph although each represents an hour. The resolution decreases.
