Although documents directly relating to the construction of the castle in Darłowo have not been found yet, the results of archaeological and architectural and historical premises allow us to date back the creation of the castle to the second half of the 14th century. It was during the reign of the prince of the House of Griffins, Boguslaw V and Elizabeth, the daughter of King Casimir the Great. The prince purchased the island with a mill in 1352 from a rich burgher of Darłowo - Elizabeth von Behr - in order to build a fortress on it. Over the decades, a castle had grown on the island, which in its main outlines has survived to this day. The work of Boguslaw V was at that time so representative that so that as early as in 1372 a congress of the Pomeranian princes - brothers and cousins Boguslaw took place within its walls. The first sovereign, who modernized the defense system and extended the castle was Prince Eric the Pomeranian. It took place in the years 1449 to 1459, when after the loss of the throne of Scandinavia, the dethroned king returned to his legacy.
In the Prussian times, the castle served partly as a warehouse and fell into ruin. Only at the end of the thirties of the 20th century, a regional museum was created there and it is operating. It founder and first curator was Karl Rosenow. Currently, the Castle of King Eric is organizing numerous exhibitions.

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.
