The sundial was constructed and set in the 18th century having been built from red squared
pedestal and standing on a square base slab. The leaded fixings remain but the bronze dial
and gnomon are missing.
What is a Sundial ?
as the horizontal sundial, the sun casts a shadow from its style (a thin rod or a sharp,
straight edge) onto a flat surface marked with lines indicating the hours of the day. As the
sun moves across the sky, the shadow-edge progressively aligns with different hour-lines on
the plate. Such designs rely on the style being aligned with the axis of the Earth's rotation.
Hence, if such a sundial is to tell the correct time, the style must point towards true North
(not the north or south magnetic pole) and the style's angle with horizontal must equal the
sundial's geographical latitude. However, many sundials do not fit this description, and
operate on different principles".
