Itanos was particularly powerful community during the Greek era and it was flourishing by the seventh century BC. Itanos was continuously at war with its neighbours Praisos, and later Hierapytna.
In the 8th century AD Itanos was destroyed in an earthquake but the inhabitants stayed and rebuilt the town. Only in the 15th century after attacks by pirates the town was finally destroyed and deserted. Because the west of Crete slowly elevates upwards and the east odf the island is slowly sinking (6 to 9 meters in the last 2000 years, mainly caused by earthquakes) parts of the harbour of Itanos have now sunk into the sea.
Herodotos was the first Greek historian who mentioned Itanos. The archeological site of Itanos is open to the public. It is possible to see the ruins of houses, city walls and Christian churches. Many Greek inscriptions were found in situ; the most famous one, kept now in the monastery of Toplou, relates a decision by the Roman Senate about Itanos' conflicts and territorial disputes with the neighbor cities Praisos and Hierapytna.
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.
