A JOURNEY THROUGH HISTORY

Two Eras, One Timeless Monument

Little Hagia Sophia is one of Istanbul's most remarkable examples of a monument shaped by different civilizations.

Originally built in the sixth century during the reign of Emperor Justinian I, the Church of Saints Sergius and Bacchus reflected the architectural ambition and artistic achievements of the Byzantine Empire.

Centuries later, during the Ottoman period, the building was converted into a mosque under the patronage of Huseyin Aga, an official associated with the reign of Sultan Bayezid II.

Although its religious function changed, the monument retained much of its distinctive Byzantine architecture. Today, known as Küçük Ayasofya Mosque, it stands as a powerful reminder of Istanbul's rich and layered cultural heritage.

BYZANTINE ROOTS, OTTOMAN HERITAGE

A Sacred Space Transformed

The story of Little Hagia Sophia begins in the sixth century, when Emperor Justinian I commissioned the Church of Saints Sergius and Bacchus in Constantinople.

With its distinctive central dome, elegant columns, and richly detailed interior, the church became an outstanding example of early Byzantine architecture.

Following the Ottoman conquest of Constantinople in 1453, the city entered a new era. During the reign of Sultan Bayezid II, the historic church was converted into a mosque through the patronage of Huseyin Aga.

The building was adapted for Islamic worship while preserving much of its original architectural character. Byzantine craftsmanship and Ottoman additions came together, creating a monument that reflects centuries of cultural and religious change.

Today, Little Hagia Sophia continues to serve as a mosque and remains one of Istanbul's most fascinating historic landmarks.
