The current Stone Bridge in Skopje across the Vardar River was built on Roman foundations under the patronage of Sultan Mehmed II the Conqueror between 1451 and 1469. Most of the bridge originates from the Ottoman period and throughout the centuries, the Stone Bridge was often damaged and then repaired. There is historical evidence that it once suffered during the great earthquake of 1555 which heavily damaged or destroyed four pillars. Renovations were carried out the same year. Some executions have also taken place on this bridge, such as the execution of Karposh in 1689.
In 1944, explosives were placed on the bridge by Nazis. Upon a request from city notables, the Germans give up at the last minute and the bridge was saved from destruction. The last reconstruction of the bridge began in 1994. Over seven years during the Stone Bridge refurbishment of the 1990s, people were not allowed to cross the structure and for many craftsmen from the nearby Old Bazaar it resulted in negative economic effects. The watchtower shaped like a mihrab was reconstructed in 2008.
The bridge is considered a symbol of Skopje and is the main element of the coat of arms of the city, which in turn is incorporated in the city's flag.
The Stone Bridge is built of solid stone blocks and is supported by firm columns that are connected with 12 semicircular arcs. The bridge is 214 m long and 6 m wide. The guardhouse has recently been reconstructed.
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.
