According to some historical sources, Dragonara Castle was built in the first half of the 13th century. In the second half of the 14th century, the castle, to ensure the safety of the fishing village of Camogli, was repeatedly reinforced, receiving the necessary weapons from the Republic of Genoa.
In the 14th century, the Dragonara Castle was attacked several times. Well documented are the assaults made by Gian Galeazzo Visconti, Lord of Milan, and the one made by Nicolò Fieschi in 1366.
Between 1428 and 1430, the castle was considerably enlarged and reinforced, especially the adjacent watchtower. In 1438, the Duchy of Milan besieged the castle, destroying its walls. A few years later, the inhabitants of the seaside village built new walls around the castle.
In 1448, due to a conflict between Camogli, Recco and Genoa, the Republic demanded the immediate destruction of the castle. The castle was destroyed, but it was rebuilt again only six years later and given to the Doge of Genoa.
In the 16th century, the castle was abandoned as a defensive post, and it was used as a prison.
In the seventies of the 20th century, after decades of neglect, the building was recovered and converted into an aquarium, hosting specimens of the marine fauna typical of these waters. At the closing of the aquarium, the fish were transferred to the Genoa aquarium.
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.
