1.1. EXPLORATION OF ISTANBUL’S ICONIC LANDMARKS
In our exploration of Istanbul’s timeless icons, we will traverse through the architectural brilliance of Hagia Sophia, the spiritual sanctuary of the Blue Mosque, the imperial grandeur of Topkapi Palace, and the subterranean marvels of the Underground Cistern. Every location tells a different part of Istanbul’s history and demonstrates a city where the past and present interact to create a timeless whole.
HAGIA SOPHIA: An Architectural Marvel
Hagia Sophia was built as a Christian church in the 6th century (532–537) under the direction of the Byzantine emperor Justinian I. Over the centuries, Hagia Sophia underwent significant religious transitions. After the Ottoman Empire conquered Constantinople in 1453, the cathedral was converted into a mosque by Sultan Mehmed II. It remained a mosque for almost 500 years. In 1935, Hagia Sophia was secularised and transformed into a museum under the leadership of Mustafa Kemal Atatürk, the founder of the Republic of Türkiye. The secularization was part of broader efforts to modernize Türkiye and separate religion from the state.
Hagia Sophia’s architectural and historical significance led to its designation as a UNESCO World Heritage Site in 1985. Its inclusion recognizes its importance in Christian and Islamic traditions and its influence on architectural development. The architecture of Hagia Sophia is a blend of Byzantine and Ottoman styles. The massive dome, an engineering marvel of its time, has inspired countless structures throughout history.

The central dome of Hagia Sophia is one of the largest in the world, spanning 31 meters (102 feet) in diameter. The addition of minarets during its transformation into a mosque altered the exterior silhouette, adding a distinct Ottoman touch to the structure. In July 2020, Hagia Sophia underwent a significant transformation once again. Turkish authorities decided to revert its status to a mosque, allowing regular Islamic prayers. This move sparked debate due to its cultural and historical significance.
