In the northeast corner of the Archaeological Park there is a long street strewn with graves from the Greek, Roman and Byzantine periods, which were carved into the limestone cliffs here. Among them there is also the famous 'tomb of Archimedes', which can be recognized easily by its gabled façade. According to legend, the famous mathematician, who died during the Roman siege of Syracuse in 212 BC, is buried here. However, even the Roman writer Cicero noted that Archimedes was buried in front of the gate to Agrigento. The supposed grave of Archimedes is a Roman columbarium from the 1st Century A.D.
References:The Clementinum is a historic complex of buildings in Prague. 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.
