Your half-day Istanbul excursion begins when you’re met at the port, airport, or your hotel and head out on a guided tour of this historical city. Visit Hagia Sophia, an architectural marvel that was constructed as a basilica in the 6th century by Emperor Justinian. It later became a mosque and today is one of the city’s important museums. See the Blue Mosque, which is situated on a site that faces Hagia Sophia. It is best known for its blue Iznik tiles and is unique in that it features 6 minarets. You’ll also explore the ruins of the ancient Hippodrome, once the center of chariot races and athletic and political events in Constantinople. At the end of the tour you’ll be transferred to your meeting point.
