Galata Bridge

The Galata Bridge is a bridge that spans the Golden Horn. In the years 1502–1503 there were plans to construct the first bridge at the current location. Sultan Bayezid II solicited a design and Leonardo da Vinci, utilizing three well-known geometrical principles, the pressed-bow, parabolic curve and keystone arch, created an unprecedented single span 240 m long and 24 m wide bridge for the Golden Horn, which would have become the longest bridge in the world of that time if it had been constructed. However, the ambitious design was not approved by the Sultan. A smaller scale version of Leonardo da Vinci's Golden Horn Bridge was brought to life in 2001 near Oslo, Norway by the contemporary artist Vebjørn Sand, the first civil engineering project based on a Leonardo da Vinci sketch to be constructed. The Leonardo Bridge Project hopes to build the design as a practical footbridge around the world, including the Golden Horn in Istanbul, using local materials and collaborating with local artisans as a global public art project.
