Want to discover the Istanbul of Byzantine Constantinople? Have you finished the famous sites in Sultanahmet and ready to walk in areas where tourists do not go? Then this Byzantine Istanbul (Constantinople) tour along the Golden Horn will be the perfect choice for you. The vastness of the vision and boldness of the design of Byzantine era Constantinople is expressed through the Hagia Sophia located in Sultanahmet but medieval Constantinople around the Golden Horn offers more information. Poke around forgotten corners just over this hauntingly beautiful inlet – the Golden Horn and walk to see Constantinople before the Ottoman Conquest of 1453. Your Byzantine Istanbul Constantinople tour will start with a ferry ride from Eminonu or Karakoy zigzaging both sides of the Golden Horn to end in Ayvansaray. Ayvansaray is where Constantinople officially ended, so you’ll see and walk along the mighty Byzantine walls of Theodosius from the 5th century. Your first visit will be to an extraordinary Greek Orthodox Church – Mary Blachernae. The only church in the whole world where there’s a service on a Friday morning. Built on a sacred water source, the church is a pilgrimage site for the Greek people in Istanbul. Climb the 7th hill of Istanbul as you make your way to one of the oldest Byzantine palaces from the 13th century (Tekfur Sarayi). Then, walk your way back through Balat which houses one of Istanbul’s surviving mediaeval synagogues and trendiest houses that are now enjoying their second or even third type of use. In Fener, you will see the Greek Orthodox patriarchate housing a column, which is believed to have been used for the binding and flogging of Jesus in Jerusalem.
