Take a half-day or full-day walking tour of Istanbul's old city of Sultanahmet with an expert guide. Your guide structures your tour to showcase the places that were highlighted in Dan Brown`s best-selling book Inferno.
Visit key sites where the main character, Robert Langdon, untangled the murky webs of Dan Brown's captivating mystery. Admire the World Heritage-listed Hagia Sophia (with the Deesis mosaic and the tomb of duke Enrico Dandolo). Go underground at the Basilica Cistern (where the virus was hidden in the novel, close to the Medusa head). Stroll around the Hippodrome (where four bronze horses were once located; they are now in Venice in St Marc Church). Pass by the New Mosque, built in the 1600s, as you walk to the Spice Market. From there you can enjoy clear views of Galata Bridge.
Upgrade to a full-day tour that includes a relaxing boat trip on the Bosphorus River. Afterward, stroll through the bustling streets to the Grand Bazaar and soak in the atmosphere described in the novel. Your tour ends in Grand Bazaar where you can explore the shops further on your own.
