Melgund Castle, lying around two kilometres due east of Aberlemno, is a 16th-century L-plan castle which has been partially restored as a private residence.
The land was initially held by the Cramonds, but it passed to the Clan Bethune or Beaton. castle has been said to have been built in 1543 on the orders of Cardinal David Beaton, Archbishop of St Andrews and Chancellor of Scotland, as a home for himself and his mistress, Margaret Ogilvie. However, Charles McKean has argued that the work of the 1540s was a re-modelling of an earlier building. Other sources believe that the builder of the castle was probably David Bethune, son of the Cardinal and Ogilvie, and date the building to about 1560. It much later passed by marriage to the Earls of Minto, who were granted the title Viscount Melgund, presently used by the heir to the earldom. It remained in the family until it was sold in 1990.
The castle was extensively investigated by archaeologists between 1990 and 1996 in preparation for its partial conversion into a residence. The work was completed in August 2002, mostly using local materials which included stone from a specially re-opened quarry nearby. The domestic range to the east of the keep has been retained in its ruined state and the primary exterior difference is the new roof to the keep.
It comprised a four-storey keep with an attic and a stair tower that appears to have been raised to act as a watchtower. Its two-storey domestic range on the east had a round tower at the north-east corner.
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.
