Italian renaissance man, Leonardo da Vinci remains one of the most famous artist, architect, engineer, scientist, naturalist and inventor from his or any other generation. Many of his concepts were hundreds of years ahead of their time, and Golden Horn Bridge is a perfect example of that.

In 1501, Leonardo da Vinci made a sketch of a 240-meters long single span bridge that was to be built over the Golden Horn – a natural inlet of the Bosphorus Strait dividing the city of Constantinople, present day Istanbul. This was the first time that such a long single span bridge was proposed. The construction methods that would be required to build such a structure would not come into use for another 300 years. Consequently, the bridge could not be built because it was too advanced for the builders of that time.
