In Four Istanbuls, Radi Dikici narrates the story of 2600 years old Istanbul, the queen of all cities, from her founding by King Byzas in 657 BC until the fall of the Ottoman dynasty in 1924.

Dikici reveals the history of Istanbul in four different periods, namely Byzantion (Byzantium), Augusta Antonina, Constantinople (New Rome) and the Ottoman İstanbul, different in many ways yet similar in sharing a common legacy.
