This was a particularly confusing period in the welding of the nation. King Alexander 1st was on the throne and his brother David (1st) was Prince of Cumbria which was an area around the borders. Although this did not include Galloway where David was increasing his influence in that area. When Alexander died in 1124 David with the backing of the English throne decided to take over Alba which was most of the rest of Scotland. This started a ten year conflict against the son and heir of Alexander.

When the Hunters settled in they would certainly have needed a strong point for protection in these uncertain times. In these days when life could be short and brutal, wood, which was in plentiful supply and easy to work was the normal material used. King Alexander the third continued to secure the Kingdom carrying on the task his father had set and one ongoing problem was the west coast. The King issued instructions to his lieges in the area to reinforce their defences and it would have been at this time that the start of Hunterston castle as we know it was begun. There was probably a system of early warning set up along the coastal defences. Alexander had given warning to King Haaken who claimed lands in the area and in the resulting "Battle of Largs" in 1263 the area was well prepared.
