The New Fortress of Corfu is a Venetian fortress built on the hill of St. Mark in Corfu. The current buildings which exist within the fortress were built by the British during their rule of the island (1815–63).
In the aftermath of the first great Ottoman siege of Corfu in 1537, the Venetians developed plans to expand the fortifications of the city. Venetians built the New Fortress at the hill of St. Mark to further strengthen the defences of the outer city of Corfu and to act as the focal point of the new fortifications. The exact dating of the structure is not established but accounts vary between 1576 or 1577-1588, and 1572-1645.
The sea defences of the New Fortress were destroyed by the British when the British protectorate came to an end and Corfu was united with Greece in 1864. Under the same agreement, the Avrami and Vido island forts were also destroyed. When the latter fort was demolished, the explosion was so strong that it broke house windows on the Corfu side of the sea channel.
At the top of the castle there is a stone building which was used for defence and a brick building which in modern times functions as the headquarters of the Naval Station of Corfu. The Venetian fortifications were later expanded by the British and the French to help defend against a possible Turkish attack. Its fortifications included 700 pieces of artillery with range estimated as far as the Albanian coast.
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.
