Newark Tower is a large, ruined tower house in the valley of the Yarrow Water three miles west of Selkirk in the Scottish Borders. It was granted to Archibald Douglas, Earl of Wigtown around 1423. It was incomplete at this time and work continued until about 1475. The surrounding barmkin was added around 1550, and the present battlements and two square cap-houses date from about 1600.
After the fall of the Black Douglases the Tower was held by the crown, and in 1473 it was given to Margaret of Denmark, wife of James III. The royal arms are visible on the west gable.
Newark was unsuccessfully besieged by an English army in 1547, but was burnt the following year. In 1645, during the Wars of the Three Kingdoms, 100 royalist followers of the Marquis of Montrose were shot in the barmkin of Newark after the Battle of Philiphaugh. The Tower is believed to be haunted by the souls of the 300 slaughtered women and children also murdered at the site after the battle.
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.
