Hagia Sophia (Ayasofya) is one of the most significant architectural monuments in Istanbul and the world. It symbolizes the Byzantine, Ottoman, and modern Turkish heritage.
Construction and Byzantine Era

- Purpose: Designed as the largest church of the Byzantine Empire and its central religious structure.
- Feature: It was the largest enclosed space in the world upon completion, with a dome that represented a revolutionary engineering achievement.
Architectural Features
- Dome: 31 meters in diameter, 55 meters high. Supported by four massive piers. It collapsed several times due to earthquakes and was reinforced, especially during the Ottoman era (notably by architect Mimar Sinan).
- Mosaics: Rich Byzantine mosaics depicting Christ, the Virgin Mary, and saints.
