Kadırga Square and the Old Kadırga Harbour

From Julian to Sophia: a vanished Byzantine harbour

Constantinople's Marmara shore was lined with artificial harbours for ships that wanted to dock on the city's southern side rather than round the point into the Golden Horn. According to historical sources, one of them was built in the 4th century under Emperor Julian and named after him. In the later 6th century Justin II had it dredged and enlarged and renamed it after his wife, Empress Sophia, which is why Byzantine texts use both names.

For centuries the harbour served ships carrying grain, timber and stone into the city. But the sand and silt brought by the Marmara currents meant constant dredging, and as maintenance faltered in the late Byzantine period the basin slowly shrank.

Harbour of the galleys: Kadırga under the Ottomans

After 1453 the Ottomans used the old basin for a time for galleys, the oared warships that gave the district its name. When the navy's main base moved to the Imperial Arsenal on the Golden Horn, the harbour lost its purpose, was left to silt up and gradually disappeared beneath mansions, houses and gardens. The Sokollu Mehmed Pasha Mosque, built on the slope by Mimar Sinan in 1571–1572, shows how prestigious the neighbourhood had become.

Street names still remember the water: one of the roads leading into the square is still called Kadırga Limanı (Kadırga Harbour). Look at how flat and open the square is compared with the steep lanes around it, and it is easy to imagine that boats once floated here.

Kadırga today: real neighbourhood life

Today the square is a tree-shaded park ringed by modest apartment blocks, small shops, bakeries and tea stalls. In the late afternoon children race around the playground, retirees chat on benches and students share sesame bread rings on their way home from school. After the postcard views of Sultanahmet, sitting here for a few minutes gives you the city's real rhythm.

Walk west and you reach the historic churches and lanes of Kumkapı; head south and, past the railway and the walls, you come to the Marmara shore. Kadırga works as a natural hinge between neighbourhoods.

What to notice as you walk

• The walls of Sokollu's madrasa: look up the slope from the square and Sinan's stonework stands out immediately.
• Traces of the harbour: the level ground and the street names help you picture roughly where the Byzantine basin lay.
• Neighbourhood fountains: keep an eye out for small Ottoman street fountains with inscriptions in the surrounding lanes.
• Towards the sea walls: heading downhill to the south you catch glimpses of the Marmara sea walls.

Getting there from Sareban Hotel
