Elcho Castle is located a short distance above the south bank of the River Tay. It consists of a Z-plan tower house, with fragments of a surrounding wall with corner towers. The fastle was built on the site of an older structure about 1560, and is one of the best surviving examples of its date in Scotland. A large portion of the Castle is accessible, although floors in some rooms have fallen, and much of the building can be walked through. The wall-walk is accessible at two points.
The property is still owned by the family of the original builders, the Wemyss family (the style of the heir to the Earl of Wemyss is Lord Elcho), though it has not been inhabited for some 200 years. It has nevertheless been kept in good repair - one of the earliest examples in Scotland of a building being preserved purely for its historical interest. It is managed by Historic Environment Scotland as a scheduled monument.
The castle is open to visitors throughout the summer. There is an entrance charge.
An apple- and pear-tree orchard adjoining the castle has been replanted in recent years, and a 16th-century 'beehive' doo'cot (Scots for dovecote) survives nearby.
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.
