The Cittadella of Alessandria is a star fort and citadel in the city of Alessandria, Italy. It was built in the 18th century by the Kingdom of Sardinia, and today it is one of the best preserved fortifications of that era. It is one of the few fortifications in Europe still in their original environment, since there are no buildings blocking the views of the ramparts, or a road that surrounds the ditches.
The fortress extends over 74 hectares whose longer side is parallel to the axis of the river. The Citadel is a perfect example of modern fortress composed of six bastioned fronts supplied with cavalieri crossed by tunnels and casemates. The fortress is surrounded by a wide moat, in connection with the Tanaro river through flooding tunnels, scheduled to be flooded by the waters of the river, and protected by tenaglioni, ravelins, counterguards and ridottes.
The citadel was besieged first time between 1745 and 1746 when it resisted the French-Spanish army for seven months, during the War of the Austrian Succession. At the end of the First Italian Campaign, the Citadel was in the hands of the French: in July 1799 it was under siege by the Austro-Russian Army led by Aleksandr Vasilyevich Suvorov. After three days of bombing were inflicted serious damage to the fortified structures and the French were forced to surrender.
In 1814 the Austrian army captured the fort and transferred it to the restored Kingdom of Sardinia. The fort was renovated, and by the mid-19th century it became an important bulwark against the Austrian Empire.
On 10 March 1821, during the Piedmont insurrection, the blue, red and black tricolour of the Carbonari was raised on the Cittadella's bastions by Colonel Ansaldi. This was the first use of a tricolour flag in the history of Italy.
IIn 2010, a permanent exhibition of about 1500 uniforms, weapons and memorabilia of the Royal Italian Army was established within the fort.

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.
