Edzell Castle is a ruined 16th-century castle, with an early-17th-century walled garden.
The first castle at Edzell was a timber motte and bailey structure, built to guard the mouth of Glenesk, a strategic pass leading north into the Highlands. The motte, or mound, is still visible 300 metres south-west of the present castle, and dates from the 12th century. It was the seat of the Abbott, or Abbe, family.
The construction of current castle was begun around 1520 by David Lindsay, 9th Earl of Crawford, and expanded by his son, Sir David Lindsay, Lord Edzell, who also laid out the garden in 1604. The castle saw little military action, and was, in its design, construction and use, more of a country house than a defensive structure. It was briefly occupied by English troops during Oliver Cromwell's invasion of Scotland in 1651.
In 1715 it was sold by the Lindsay family, and eventually came into the ownership of the Earl of Dalhousie. It was given into state care in the 1930s, and is now a visitor attraction run by Historic Environment Scotland (open all year; entrance charge). The castle consists of the original tower house and building ranges around a courtyard. The adjacent Renaissance walled garden, incorporating intricate relief carvings, is unique in Scotland. It was replanted in the 1930s, and is considered to have links to esoteric traditions, including Rosicrucianism and Freemasonry.
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.
