Caerlaverock Castle is an impressive and unusual triangular-shaped castle a few miles South of Dumfries on the Solway coast. With its moat, two-towered gatehouse, and imposing battlements, it is a fine example of a medieval stronghold. The castle's turbulent history owes much to its proximity to England which made it a strategic objective in Border conflicts.
Caerlaverock castle was originally built in the 13th century. It was a stronghold of the Maxwell family from the 13th century until the 17th century, when the castle was abandoned. It was besieged by the English during the Wars of Scottish Independence, and underwent several partial demolitions and reconstructions over the 14th and 15th centuries. In the 17th century, the Maxwells were created Earls of Nithsdale, and built a new lodging within the walls, described as among 'the most ambitious early classical domestic architecture in Scotland'.
In 1640 the castle was besieged for the last time by the Protestant Covenanter army and was subsequently abandoned. Although demolished and rebuilt several times, the castle retains the distinctive triangular plan first laid out in the 13th century. Caerlaverock Castle was built to control trade in early times.
The castle, which is protected as a scheduled monument, is in the care of Historic Environment Scotland, and is a popular tourist attraction.
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.
