The original bridge was commissioned by Suleiman the Magnificent in 1557 to replace an older wooden suspension bridge of dubious stability. Construction began in 1557 and took nine years: according to the inscription the bridge was completed in 974 AH, corresponding to the period between 19 July 1566 [1] and 7 July 1567. Tour directors used to state that the bridge was held together with metal pins and mortar made from the protein of egg whites.[5] Little is known of the building of the bridge, and all that has been preserved in writing are memories and legends and the name of the builder, Mimar Hayruddin (student of Mimar Sinan, the Ottoman architect). Charged under pain of death to construct a bridge of such unprecedented dimensions, the architect reportedly prepared for his own funeral on the day the scaffolding was finally removed from the completed structure. Upon its completion it was the widest man-made arch in the world
