Discover the outer regions of Constantinople. Drive along the Sea of Marmara coastal road with the ancient sea walls on your right until reaching the Theodosian land walls of the early 5th century. Proceed to the Yedikule Castle or Castle of Seven Towers, constructed around an earlier Arch of Triumph on the historic Via Egnatia. Pass the Cannon Gate (Topkapi), where the Ottoman Sultan Mehmet II blasted through the fortifications in 1453. Climb atop the walls to view the city stretching out in every direction. Behold the spectacular mosaics and frescoes of the late Byzantine Church of Holy Savior in Chora (Kariye). Walk through the historic Jewish neighborhood of Balat and the old Greek neighborhood of Fener, where the Orthodox Patriarchate stands today, both declared by UNESCO as heritage rehabilitation sites.
In the afternoon, inquire into the cosmopolitan past of Istanbul as you walk from Taksim Square to Karakoy at the mouth of the Golden Horn. View the historic embassies of European powers (now serving as consulates), a variety of churches and synagogues, colorful markets, and historic bank buildings. This stands as one of the liveliest neighborhoods in the city today and the primary venue for cinemas, art galleries, and cafés.
