Hagia Sophia History & Experience Museum

Hagia Sophia, one of the most significant monumental architectural works standing to this day, holds a unique place both for its architecture and grandeur, as well as its functionality.

Located in the renowned Defter-i Hakani (Imperial Registery) Office building in Sultanahmet, the Hagia Sophia History and Experience Museum, spanning approximately 3200 m2 of enclosed space across 13 halls, narrates the 1700-year history of Hagia Sophia.

In the museum, Hagia Sophia’s Eastern Roman and Ottoman periods are compellingly portrayed through immersive visual and auditory displays, supported by the latest technologies, offering narration in 23 different languages. Additionally, the museum features four sections showcasing a significant portion of Hagia Sophia’s collection, including artifacts exhibited for the first time from different periods: Church, Mosque, Museum, and back to Mosque. Moreover, from the ground floor windows of the building, a cistern from the Eastern Roman era can be observed.

The Hagia Sophia History and Experience Museum provides a unique experience for those who wish to immerse themselves in the rich history of Ayasofya from a holistic perspective.

The ancient city of Ephesus, listed as a UNESCO World Heritage site, stands as one of the best-preserved archaeological cities in human history. The story of Ephesus, a valuable treasure recounting the daily life, trade, religious rituals, cultures, and arts of the ancient Mediterranean civilization, is narrated to visitors in 16 different languages through the Ephesus Experience Museum, situated right across from the Ephesus Ancient Theatre within the ancient city.

The Ephesus Experience Museum employs emerging immersive technologies, gaining popularity globally and in Türkiye, to virtually transport visitors into the daily life of ancient Ephesus, almost in a real encounter. Immersive technologies envelop viewers in a rich, inclusive, and compelling auditory and visual experience.

The visual stories presented by the museum, intertwining myth and reality, take visitors to the ancient streets, festivals, temples, houses, markets, and bazaars of Ephesus during its ancient era. Visitors encounter the city’s famous figures, from its founder Androclus to Cleopatra and Marcus Antonius, and from Artemis to Saint Paul. They embark on a magical journey inside the Temple of Artemis, stroll along Harbor Street, and visit the Terrace Houses.
