At the front of the mansion house and on the turning circle called the "Hunterston House Roundabout" is a white marble well. It is not a functional well and just for decorative purposes. At each corner are large balls, they are made of solid granite stone.
When the house was open to the public in the 1980s money was dropped into the well as it was treated like a wishing well.
The inside of the well there is words inscribed on it about the Hunter family history but unfortunately the transcription I had has been misplaced but hopefully I can track down a copy.
