The Fortress of Brod was constructed between 1715-1780 by the Archduchy of Austria to create a defense against the Ottoman Empire. The city of Slavonski Brod was an important strategic and traffic center controlling the border crossing towards Turkey and connecting main commercial trails at the time. The regular star-like form of the fortress was determined by the flat-country. It was built of rammed earth, bricks, wood and partially stone, and designed for the accommodation of 4,000 soldiers, mostly infantry and 150 cannons.
The Fortress of Brod was constructed according to the Vauban system. It is basically of a rectangular form, while the system of defense channels provides its star-like layout. It consisted of three defense zones: internal, external and southern, and it was protected by two moat areas, water-fed from the nearby stream.
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.
