A local guide will accompany you all the way, starting at the Hagia Sophia. Learn about the ancient Basilica that was started by Constantine the Great in the 4th century, and completed by Emperor Justinian in the 6th century.

Admire the impressive dome and minarets, as well as the beautiful mosaics, sculptures and columns inside. Your next stop will be the legendary Sultan Ahmed Mosque, better known around the world as the Blue Mosque. Get up close to this symbol of Istanbul and see the vibrant blue tiles that adorn its interior walls. Stroll around its beautiful courtyard, and see the 6 graceful minarets. Continue to the Hippodrome, site of chariot races during the Byzantine Empire. Admire the 3 remaining monuments; the Obelisk of Theodosius, the Serpentine Column, and the Column of Constantine. End with a walk around the labyrinthine Grand Bazaar to haggle for bargains among some 4,000 jewelry, pottery, spices, carpet, and leather stores.
