Galata Bridge, the first recorded Galata bridge on the Golden Horn in Istanbul was built in the 6th century during the Great Justinian period, near the Theodosian Land Walls at the western end of the city.
In 1453, during the Fall of Constantinople, the Turks set up their mobile units by placing their ships next to each other along the water so that their troops could move from one side of the Golden Horn to another.
The Golden Horn Bridge designed by Leonardo da Vinci in 1502.
In 1502-1503, there were plans to build the first bridge at the current location. Sultan Bayezid II wanted a design, and Leonardo da Vinci created an unprecedented single span, 240 m (790 ft) long and 24 m (79 ft) wide, using three well-known geometric principles, a pressed spring, parabolic curve and keystone belt. The Golden Horn bridge, which would become the longest bridge in the world, had been built. [quote required] However, the ambitious design was not approved by the Sultan.
