9:00 a.m.: Head straight to Sultanahmet, the heart of the historic city of Istanbul. This neighbourhood is home to the most iconic attractions of the city, including Topkapı Palace, Hagia Sophia, the Blue Mosque and the Byzantine Hippodrome, among others. Keep your camera handy as you take a stroll down the lanes to soak in the rich cultural heritage of the place.
10:30 a.m.: The one-of-its-kind church-turned-mosque-turned-museum Hagia Sophia (or Ayasofya) is synonymous with the city of Istanbul, an architectural marvel and a must on your itinerary. The 55-metre high dome, the mosaics of Lord Jesus and Virgin Mary, parts of the 9th century mosaic depictions of Gabriel and Mikail, the calligraphic monogram of Sultan Abdülmecid and other such artefacts can be seen here.
