There was 6 known wells at Hunterston although only one still exists. Two were located at Hillhouse Farm but have been lost due to farming activity. Another was located at Fences Farm but was demolished in 1975 due to the building of the Power Station.
The fouth location is next to Goldenberry Road near Campbelton Hill, there is a good chance this well still exists under the grass and weeds but cannot be confirmed.
The fifth well is located between the Mansion House and Power Station next to where the Icehouse was and the well still exists and visible today.
The sixth well is the original 13th century well that was used by the castle. It is located at the side of the walled garden near the Lairds door. It survived untill 1953 when it was filled in by my grandfather.
