Cessford Castle is a large ruined mid-15th century L-plan castle near the village of Cessford, midway Jedburgh and Kelso. It1 was built around 1450 by Andrew Ker, 1st Earl of Roxburghe. It is possible that the castle incorporates parts of an earlier structure. The fortalice was built on an L-plan, with a main keep with a wing of almost the same magnitude. With up to six storeys, two of which were barrel vaulted, and with walls up to 4 m thick, it was a formidable place of defence. The castle was besieged in 1523 by the Earl of Surrey. The castle was abandoned in 1650.
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.
