The Tomb of the Eagles, or Isbister Chambered Cairn, is a Neolithic chambered tomb. First explored by Ronald Simison, a farmer, when digging flagstones in 1958, he conducted his own excavations at the site in 1976. Alerted by Simison, archaeologist John Hedges then mounted a full study, prepared a technical report and wrote a popular book that cemented the tomb's name.
16,000 human bones were found at the site, as well as 725 from birds. These were identified as predominantly belonging to the white-tailed sea eagle (Haliaeetus albicilla) and represented between 8 and 20 individuals. These were originally interpreted as a foundation deposit, however this interpretation has been challenged by new dating techniques. These reveal that the eagles died c. 2450–2050 BC, up to 1,000 years after the building of the tomb. This confirms growing evidence from other sites that the neolithic tombs of Orkney remained in use for many generations.

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.
