Constantinople capital inauguration

Istanbul

1,696 yearsfrom 330 CE to 2026

Constantinople was inaugurated as an imperial capital in 330, on the site of the older city of Byzantium. Later Byzantine and Ottoman layers transformed the city again. The age shown measures one capital milestone, not the beginning of settlement.
