The Mehmed Paša Sokolović Bridge of Višegrad across the Drina River in the east of Bosnia and Herzegovina was built between 1571 and 1577 by the court architect Mimar Koca Sinan on the orders of Grand Vizier Mehmed Paša Sokolović. Characteristic of the apogee of Ottoman monumental architecture and civil engineering, the bridge has 11 masonry arches with spans of 11 m to 15 m, and an access ramp at right angles with four arches on the left bank of the river. The 179.5 m long bridge is a representative masterpiece of Sinan, one of the greatest architects and engineers of the classical Ottoman period and a contemporary of the Italian Renaissance, with which his work may be compared. The unique elegance of proportion and monumental nobility of the whole site bear witness to the greatness of this style of architecture.
The bridge received UNESCO World Heritage Listing in 2007.
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.
