The ruins of Ardross Castle, dating back to at least the 15th century, occupy a fine defensive coastal position standing high on sandstone cliffs overlooking a sandy beach below.
In 1068 a Northumbrian knight named Merleswain came to Scotland, and was granted lands in Fife. The first mention of Ardross seems to occur in the mid-12th century. It is believed that a castle was first built on this spot by Sir William Dishington, Sheriff of Fife, who had arranged the building of St Monans Church for David II in the mid-1300s. Ardross Castle remained the seat of the Dishington family until it was sold to Sir William Scott of Elie in 1607. It seems likely that during this time the Dishingtons would have improved on and extended the original castle and, though it is hard to say for sure given the state of the ruins, it seems likely that much of what is left today dates back to the 1400s or 1500s.
In the late 1600s the castle was sold again, this time to Sir William Anstruther. It is unclear how it reached its current condition, but it looks like the castle was found to be less valuable than the stone it was made of, with the result that it was used as a quarry and recycled into nearby buildings in what is now the hamlet of Ardross.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
