Prosphorion Harbour

The Prosphorion Harbour was a harbour in the city of Constantinople, active from the time when the city was still the Greek colony of Byzantium , until the eve of the first millennium. Gradually enlarged, it was the first port to be built in the area of the future Constantinople.
The harbour lay on the southern shore of the Golden Horn, east of today's Galata Bridge, in the fifth region of Constantinople, where the sea walls made a deep nick, in correspondence of the Byzantine Gate of Eugenius , and extended successively westwards, finally occupying the first inlet after the estuary entrance. The inlet where the basin once lay is now silted up, and corresponds today to the east part of the Sirkeci railway station area, south of the Ottoman Sepetçiler köşkü. Administratively, the site belongs to the Mahalle of Hoca Paşa in Eminönü, which is part of the Fatih district of Istanbul.
