Hagia Sophia (Ayasofya)

Hagia Sophia stands as one of the world's most magnificent architectural achievements, serving as a testament to Istanbul's rich and complex history. Originally constructed as a
Byzantine cathedral in 537 AD under Emperor Justinian I, it was the largest cathedral in the world for nearly a thousand years. The building showcases an incredible blend of Christian and Islamic art, with stunning mosaics, massive dome, and towering minarets that were added after the Ottoman conquest in 1453.

This UNESCO World Heritage Site underwent extensive restoration and reopened as a mosque in 2020, though it remains accessible to visitors of all faiths. The interior features breathtaking Byzantine mosaics depicting Christian scenes alongside Islamic calligraphy and decorations. The massive central dome, supported by pendentives, was an engineering marvel of its time and continues to inspire architects today. Visitors can explore the ground floor during non-prayer times and access the upper gallery to view the famous mosaics up close
