The San Giovanni in Fiore Abbey date back to Joachim da Fiore's trip to La Sila in Calabria in 1188. Archaeological excavations have shown the presence of Joachim's first edifice, which was finished in 1198, in the Iure Vetere locality. The construction of the abbey was approved by Queen Constance of Hauteville after a Joachim's visit in her court at Palermo.
After Joachim's death in 1202, the first monastery and its annexed edifices were burned by a fire in 1214. The monks decided to abandon the location of Iure Vetere, also due to its difficult climatic situation.
In 1215 a site not far from the previous one was chosen, near the Neto river valley. The new abbey was completed in 1230, in the Romanesque style. In later centuries features were remodeled in different styles, including a Baroque style church interior.
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.
