Geisenklösterle is a cave near Blaubeuren and an important site for the European Upper Paleolithic. It is one of a number of caves where early modern humans in the Aurignacian, between 43,000 and 30,000 years ago left traces of early artwork. Geisenklösterle was first archaeologically explored in 1963. Systematic excavations began in 1973, from 1974 to 2002 sponsored by the land of Baden-Württemberg. A 1983 monographical publication summarized the results up to that time.
The cave has six levels belonging to the Aurignacian and seven levels of the Gravettian, besides earlier levels belonging to the Middle Paleolithic and later ones spanning the Magdalenian down to the Middle Ages. The Aurignacian levels date to between 43,000 and 32,000 years ago, and yielded stone tools, artefacts made from antlers, bones and ivory. Among the most notable items are a sculpture of a flutes of bird bone and mammoth ivory, the oldest known musical instruments with an age of 42,000 to 43,000 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.
