On this full-day tour, you will discover some of the most magnificent sites of historical Istanbul, coming into contact with the historical wonders of the Byzantine and Ottoman empires and uncovering the roots of modern-day Turkish culture. See the heart of the Old City, the seat of two of history's most notorious empires. Visit Hagia Sophia, a wonder of ancient architecture, a basilica constructed by Emperor Justinian in the 6th century. Just across from the Hagia Sophia stands the famous Blue Mosque with its striking blue iconic tiles and unique 6 minarets, built in the name of Sultan Ahmet. The Hippodrome was a center for sporting events, such as chariot races, as well as political activities in the Old City.

This sumptuous residence contains imperial treasures, sacred Islamic relics of the prophet Mohammed, Chinese porcelain, weapons, and more. You'll get to visit the Sultan Tombs at the Hagia Sophia, too!
