Istanbul stands at the geographical and spiritual centre of our journey, the city where Byzantine Christianity reached its architectural zenith before Ottoman conquest transformed it into Islam's greatest capital. To understand how Orthodox faith survived from Bulgaria to the Caucasus, we must first understand what was lost—and preserved—when Constantinople fell in 1453.
We begin in Sultanahmet, where Byzantine and Ottoman monuments face each other across a park that was once a Roman hippodrome. Hagia Sophia rises before us, Emperor Justinian's 6th-century masterpiece where engineering became prayer. The dome seems to float impossibly above the vast interior, suspended on shafts of light streaming through 40 windows—for 900 years, no Christian cathedral surpassed it. When the Ottomans conquered Constantinople in 1453, Sultan Mehmed II converted it to a mosque, adding minarets while leaving Byzantine mosaics largely intact. The building now preserves both Christian and Islamic elements, layers of faith visible on the same walls.
Across the park, the Blue Mosque (Sultan Ahmed Mosque) demonstrates Ottoman architectural confidence at its peak. Completed in 1616, the interior glows with 20,000 Iznik tiles in intricate floral patterns—blue, green, and white ceramics that earned the mosque its popular name. Six minarets pierce the sky, a bold statement that initially sparked controversy since only Mecca's mosque claimed more.
Our afternoon ends underground at the Basilica Cistern, a 6th-century water reservoir supported by 336 marble columns recycled from earlier Roman buildings. Two columns rest on Medusa head carvings positioned sideways and upside down—possibly to neutralize her mythical power, or simply because Byzantine engineers needed column bases and mythology mattered less than function.
The late afternoon is free for independent exploration.
NOTE: You may wonder why we choose not to include Topkapi Palace in our programme. While it's an important site with a long storied history, the nature of the facility and the rules pertaining to visitation—limits on groups and guiding to reduce crowding and noise—make it better-suited to a self-guided rather than group touring experience. Should you want to visit on your own, please consult your Tour Leader in advance.
