Located in the rolling countryside of southern County Sligo, Moygara Castle is one of the finest Gaelic castles in the north-west of Ireland. The Castle of Moygara was the principle fortress and dwelling of the O Gara family. The castle stands in a slight eminence with great views, particularly to the south. It dates from the late 16th and early 17th centuries.
The building consists of a plain rectangular tower set within a nearly square bawn withflanking angled tower at each corner. These commanded the adjacent curtain walls as well as the timber papapets that would have existed in the original building. The main entrance was on the western side where, at a later time, an entrance porch was added to the original arched opening.
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.
