Currently on its fifth rendition, the first Galata Bridge on the mouth of the Golden Horn was constructed in 1845. Also known as Cisr-i Cedid (New Bridge) to distinguish it from a 19th century bridge built atop pontoons farther upstream, the bridge was made of wood and supported by several piers that extended into the river. In addition to traversing the Golden Horn, the bridge served as a symbolic link between the two cultures of traditional, secular Istanbul and foreign, non-Muslim Galata.
