The Tito Bustillo Cave is a prehistoric rock shelter located in the small town of Ribadesella. The cave was inhabited by humans (cro-magnon) before the year 10,000 BC. Due to the collapse of the rock, the original entrance to the cave was sealed thousands of years ago, which made it possible for preservation of objects, tools and wall paintings that were discovered in 1968. Based on those objects found in the cave, it is known that there was a significant human presence during the Magdalenian culture of the Upper Palaeolithic, but the cave was probably inhabited before that time.
The Tito Bustillo Cave has been designated a World Heritage Site, as part of the Cave of Altamira and Paleolithic Cave Art of Northern Spain, and it counts with 12 prehistorical paintings, making it one of the most complete examples of the prehistoric art in the north of Spain. The oldest of these paintings shows human figures and is around 33,000 years old, as determined by radiocarbon dating. Some scientists believe it could have been made by Neanderthals, though this theory hasn't been proven.
Some of the paintings represent animals: horses, deer, moose and even a marine animal (probably a whale) and they are believed to have had some kind of ritual purpose to improve their hunting. There is also a panel representing female genitalia and it is believed to have had the intention to invoke fertility. The oldest painting in the cave represents an anthropomorphic figure, part male, part female.
Apart from the paintings, some objects from the Magdalenian period were perfectly preserved. The most important ones are some harpoons made of bone and a carved staghorn of a goat head.

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.
