Although to most people "Old Istanbul" means the historic European peninsula with Topkapı Palace, Hagia Sophia, the Blue Mosque and Byzantine Hippodrome, the first known settlement in this area was actually at Chalcedon (Kadıköy) on the Asian shore.

Take a ferry from the Eminönü ferry docks to Üsküdar, or the Marmaray from Sirkeci, visit Üsküdar's historic mosques and its lively shopping districts for a few hours, then float back to the European side, having taken an intercontinental cruisein a day!
Go south from Üsküdar by bus, taxi or Marmaray and Metro to Kadıköy, a bustling suburb with active ferry docks, city bus station, and a Metro station. Wander through the market, just inland from the ferry docks and Metro station, and the Moda neighborhood, just a few minutes' stroll south, for its pleasant tea gardens offering wonderful views of Old Istanbul.
