A Sundial for the Old School House at Durgan, Cornwall

Describes the process of commissioning and constructing a diamond-shaped vertical dial on the Old School House at Durgan, Cornwall. The wall declination was measured at 17½ degrees east of south. The slate dial is adjusted for longitude to show 'Greenwich Apparent Time' and includes a small notch for local noon. It was a collaborative effort involving the National Trust and letter carver Ben Jones.
