Aalholm Castle is the oldest castle on the Lolland island, first mentioned in the 1329. The castle was initially the seat of the king's vassal or lensmand, and thus the centre of local government. It is not known when the castle was founded, but for historical reasons, it was probably around 1200. During this period, a number of royal castles were built across the country to strengthen the king's power in the regions and guard against attack.
Aalholm was located on a very favorable site, standing on a little island in the inlet known as Nysted Nor. Completely surrounded by water, it was protected from the open sea although ships of all kinds could sail right up to the island, provided they had crews conversant with the channel to be followed. Not far to the north and west, there was fertile land where produce could be grown for the castle, with a surplus for the vassal and the king. The importance of the area at the time can also be appreciated from the fact that the Franciscan monastery in Nysted, built in 1286, was the only one on the islands, especially as the Franciscans always settled in thriving, populated areas where they could rely on the support of the inhabitants.
However, it is impossible to trace the early history of the castle as there are no written sources and any archaeological evidence is hidden beneath today's building. The castle has been built and rebuilt even since it was founded. The oldest part of the existing building is the north wing, thought to date from the 14th and 15th centuries. Thereafter, there is plenty of documentation on restoration and refurbishment, sometimes also revealing the poor state of the building. For example, in the 1550s, bricks from the Franciscan monastery were used to repair the castle while after the Swedish Wars of 1657-1660, the building had no windows and the towers no roofs. In the 18th century, parts of the south wing were demolished and the east wing was fully renovated. In 1889, a further section of the south wing was pulled down and two new lateral wings were added on the south side of the north wing. As a result, the once rectangualar structure now took on a shape resembling a pair of spectacles. Since then there have been no significant changes to the castle's exterior.
In the 1970s, parts of the castle were opened to the public as a museum, while the former owner established a vintage car museum on Stubberup Farm about one kilometer to the west of the castle. In connection with the sale of the castle and estate in 1995, all the furnishings were auctioned off while the new owner took over the automobile museum. The museum was closed in 2008 owing to the poor state of the buildings.

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.
