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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
