Memorial of the battle of Crécy (26 August 1346) was built in the place of a windmill where the king of England waited for the attack of the king of France. The battle of Crécy was one of the most important battles of the Hundred Years' War because of the combination of new weapons and tactics used. The English knights knew the importance of being willing to fight dismounted elbow to elbow with the pikeman and archers, a procedure which was learned from the earlier Saxons and also by their battles with the Scots from whom they learned tactical flexibility and the adaptation to difficult terrain. All of these factors made Edward III's army powerful, even when outnumbered by the French forces.
The size of the forces are not known exactly. Some historians have agreed on estimates of around 10,000–15,000 on the English side and 20,000–25,000 on the French side. The battle ended to the decisive English victory. At least 2,000 French knights and unknown number of common soldiers died. The English army lost only 100-300 men. Due the victory Calais became an exclave of England. It shook France to the core and established an English presence in France that was to last for over one hundred years.

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.
