When the Turks invaded Mostar, there was a wooden bridge at the place of today's Old Bridge; it hungs on chains, over which one had to pass very cautiously. As it became worn out in the middle of the 16th century, the people of Mostar asked authorities in Istanbul to build a new bridge from quality material. It was designed by the builder Hajrudin, pupil of the famous Sinan, the great Turkish architect of the 16th century. The Old Bridge was completed and and put into service in July or August 1566. Its span is 28,70 meters and it has only one big stone arch. It is 4,49 m wide, while the height from the summer water level is 21 m. The bridge was built of square stones connected with iron hooks and cast in lead. Every passer-by stops here to admire this masterpiece. Mostar is known for its bridge all over the Europe and the world. The central part of the old town, with its forts, towers and gates, developed around this magnificent monument producing a unique architectural whole.
