Château de Josselin was built in the 11th century and rebuilt at various times since. Guéthénoc, vicomte of Porhoët, Rohan and Guéméné, began to build the first castle on the site around the year 1008, choosing a rocky promontory overlooking the valley of the Oust. The site chosen for the castle was excellent from both the commercial and the military points of view, and since the 9th century there had also existed an annual pilgrimage in September to the Basilica of Our Lady of the Bramble (Notre-Dame du Roncier), which added greatly to the wealth of the lords and people of Josselin.
In 1154, Odo, Viscount of Porhoet, step-father, guardian and regent of the young Conan IV, Duke of Brittany, collected the Breton lords to deprive Conan of his inheritance, but was defeated by Henry II of England, who was also Duke of Anjou, whose protection Conan had sought. Henry married his fourth son, Geoffrey, to Conan's only child, Constance, Duchess of Brittany, and Henry and his son pulled Josselin Castle down in 1168 and 1175. Henry II himself led the demolition and sowed salt into the ruins.
During the Breton War of Succession (1341-1364), the garrison of Josselin fought inconclusively the defenders of the nearby Castle of Ploërmel. To break the impasse, the Battle of the Thirty was arranged, contested by thirty knights from each side, and took place on 26 March 1351 halfway between the two places. The men of Josselin defeated the champions of Ploërmel, who consisted of four Bretons, six Germans, and twenty Englishmen.
In 1370 the Breton soldier Olivier de Clisson (1336-1407), later Constable of France, acquired the lordship of Josselin and built an imposing new fortress with eight towers and a keep one hundred yards across. He married his daughter Beatrice to Alain VIII of Rohan, heir to the viscounts of Rohan, whose own castle was not far away. The castle now boasts an equestrian statue of Olivier de Clisson.
In 1488 Francis II, Duke of Brittany, took the castle and partially demolished it. His daughter, Anne of Brittany, restored it to Jean II of Rohan, a great-grandson of Olivier de Clisson, who transformed the property and built a noble new house with a fine granite facade, an early example of Renaissance architecture, importing Italian artists and artisans. In recognition of his patroness Anne, sovereign Duchess of Brittany and Queen Consort of France, Rohan added to the facade at several points the sculpted letter A beneath a cord, her badge.
Banned from Josselin due to their Protestantism, René II, Viscount of Rohan and the other Rohan men could not prevent the Duke of Mercœur, then Governor of Brittany, from turning their castle into a base for the Catholic League in its struggles against Henry IV of France.
In 1603, after being advanced by Henry IV to a dukedom, Henry, Duke of Rohan, one of the leaders of the insurgent Huguenots, transferred his military headquarters to his Castle of Pontivy. In 1629, Cardinal Richelieu dismantled the keep and four of the towers at Josselin. In the 18th century, the castle was no longer occupied as a seat of power, and during the years of the French Revolution and the First French Empire it became a prison and warehouse. In 1822, Caroline, Duchess of Berry, persuaded the then Duke of Rohan, Louis François de Rohan-Chabot, to restore it.
The Antechamber of the castle contains a marble bust of the 13th Duke, Alain Louis Auguste de Rohan-Chabot, sculpted in 1910 by Auguste Rodin. The Castle is still a residence of Josselin de Rohan, fourteenth Duke of Rohan.

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.
