The lands of Craigcrook were, in the 14th century, in the possession of the Graham family. In 1362 the lands were given to the chaplains of St. Giles' Cathedral. They passed through several more owners before 1542, when William Adamson, a merchant and burgess of Edinburgh, took possession. The Adamson family constructed, or reconstructed, Craigcrook Castle, and owned it until 1659.
It is not known when the castle itself was constructed. From the style of building, the majority of the castle has been dated to the early 17th century. However, the nature of the vaulting inside suggests that the core of an earlier fortalice was extensively rebuilt or extended at this time.
A billiard room was added to the east by Robert Croall in about 1891, the architect being Thomas Leadbetter. Another extension was added, after the property became the base for an architectural practice, in 1968.
A 17th-century wall still encloses the garden which has a roll-moulded arched gateway, the pediment of which is dated 1626.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
