Leonardo Da Vinci Bridge , Ponte di Galata , Ponte di Galata di Leonardo Da Vinci sul Corno D'Oro
nie errichtet [abgesagt]
In 1502 Leonardo Da Vinci designed a bridge that would span the Golden Horn in Istanbul, upon request from the Ottoman emperor Bayezid II.
The bridge would have a length of 240 meters, a width of 23 meters, and a height (over sea level) of 40 meters according to Leonardo Da Vinci's design.
If built, it would have become the world's longest bridge of that time (1502) with its length of 240 meters.
The project was rejected by Sultan Bayezid II who didn't believe that it could be realized.
The basis of the construction - three arches supporting a walkway - was first accepted as an engineering principle 300 years after Da Vinci made his drawing, confirming his reputation as a man ahead of his time.
Da Vinci was so convinced by his project that he had even offered to build it himself. In a letter he wrote to the Sultan - which was found in 1952 at the Topkapi Palace archives - the great master expressed his wish to come to Istanbul in order to personally realize his project.
