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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
