This small village of Castelmola is a real genuine natural terrace built around the ruins of a Norman castle. The Norman walls are all that remain of the fortress.
A plaque from the tenth century with Greek-Byzantine engravings placed on the façade of the cathedral states: This castle was built under Costantino, patrician and strategist of Sicily. It is probably referring to Costantino Caramalo, who in the ninth century defended the bastion, city and territory from attacks by the Arabs.
The centrality of the castle of Mola is historically proved not only in the Middle Ages, but also in the wars between the French and Spanish. Once you entered the village through a gate carved into the rock right at the base of a stairway made from white lavastone.
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.
