Cairnie was a property of the Lindsay family, later Earls of Crawford, from 1355. The tower was constructed around 1500 by Alexander Lindsay of Auchtermoonzie (d.1517). The second son of the 4th earl of Crawford, Alexander subsequently became 7th earl, inheriting the earldom from his nephew who was killed at the Battle of Flodden in 1513. According to John Knox, James V of Scotland visited the castle just before his death in 1542. It was unoccupied in the 17th century, and was used for religious meetings by an outlawed Episcopal congregation. It was later used for agricultural purposes.
It was originally an L-plan tower house with five storeys, including a barrel-vaulted basement and a garret. The stair tower is located on the north-west side, linking all floors from a ground floor entrance. The parapet and many of the dressed stones forming the window surrounds have been lost. To the north-east is a single round tower, once flanking a gate within an outer enclosure wall.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
