The Venetian Arsenal is a complex of former shipyards and armories clustered together in the city of Venice. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power during the centuries. It was one of the earliest large-scale industrial enterprises in history.
Construction of the Arsenal began around 1104, during Venice's republican era. It became the largest industrial complex in Europe before the Industrial Revolution, spanning an area of about 45 hectares, or about fifteen percent of Venice. Surrounded by a 3.2 km rampart, laborers and shipbuilders regularly worked within the Arsenal, building ships that sailed from the city's port. With high walls shielding the Arsenal from public view and guards protecting its perimeter, different areas of the Arsenal each produced a particular prefabricated ship part or other maritime implement, such as munitions, rope, and rigging. These parts could then be assembled into a ship in as little as one day. An exclusive forest owned by the Arsenal navy, in the Montello hills area of Veneto, provided the Arsenal's wood supply.
The Arsenal produced the majority of Venice's maritime trading vessels, which generated much of the city's economic wealth and power, lasting until the fall of the republic to Napoleon's conquest of the area in 1797.
Significant parts of the Arsenal were destroyed under Napoleonic rule, and later rebuilt to enable the Arsenal's present use as a naval base. It is also used as a research center and an exhibition venue during the Venice Biennale, and is home to a historic boat preservation center.

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.
