The earliest records of Kellie go back to 1150 where it is mentioned in a charter issued by King David I. The first known owner was Robert of London, the illegitimate son of King William the Lion. None of the early buildings to have survived.
The estate was signed over to a Siward relative, Walter Oliphant, in 1360 and the castle remained in the ownership of the Oliphant family until 1613. It was purchased by Sir Thomas Erskine, who had saved the life of King James VI during the Gowrie Conspiracy. The King stayed at Kellie in 1617 during his only visit to Scotland after the Union of the Crowns, and he appointed Erskine as Earl of Kellie in 1619.
Originally a simple tower house, the lower section of what now constitutes the northwest tower is the oldest part of the castle, dating from around 1360, and is said to be haunted. In 1573 a new tower was built by the 4th Lord Oliphant to the east of the original tower. It is believed that the 4th Lord built the east tower as a jointure-house (a property set aside for the wife after the husband's death) for his wife Margaret. Between 1573 and 1606 the two towers were linked by a new range, terminated by another tower in the south-west, creating the T-plan layout that remains today. The castle is a fine example of Scots Baronial domestic architecture, with an imposing mix of gables, corbelled towers, and chimneys.
The walled garden is 17th century, with late Victorian additions, contains a fine collection of old-fashioned roses, fruit trees and herbaceous plants.
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.
