Audley's Castle is a three-storey tower house named after its 16th century owner, John Audley.
There are thousands of small stone towers similar to Audley's Castle in the Irish countryside. They are one of the commonest of archaeological sites, which indicates these were not buildings put up for the higher aristocracy, but for lesser lords and gentry. Most were built in the late Middle Ages (roughly 1350–1550). Audley's was built towards the end of this period.
There is very little historical information about the buildings in the small courtyard around Audley's. Only a minority of towers had courtyard walls at all, and their buildings were clearly less important than the tower. The towers in different parts of the country vary, with distinct regional patterns. Audley's with its two turrets linked by an arch is one of a type found in County Down only.
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.
