Tucked near the Sea of Marmara in Istanbul’s historical peninsula stands Little Hagia Sophia, once known as the Church of Saints Sergius and Bacchus. It was built between 527 and 536 AD by Emperor Justinian I, just before he commissioned the grand Hagia Sophia. In many ways, this church served as a test model. Its central dome and innovative spatial design were prototypes for what would soon become the architectural marvel of Byzantium.

What makes it unique among Byzantine churches is precisely this role: an experimental structure that bridged classical Roman forms with what would become defining traits of Byzantine sacred architecture. Its intimate scale, octagonal nave, and decorative capitals speak of both ambition and elegance.
Despite the name, Hagia Sophia isn’t a person. It means “Holy Wisdom,” a theological concept personified in Christ by early Christians. So, neither the great nor the little Hagia Sophia were named after a woman, but after divine wisdom.

After the Ottoman conquest in 1453, the church was converted into a mosque, Küçük Ayasofya Camii. The Ottomans preserved its core structure, adding Islamic elements like a minaret and mihrab, integrating it into their culture.
Beneath the bustling streets of Istanbul’s old city lies a silent forest of stone — the Basilica Cistern, known to the Ottomans as Yerebatan Sarnıcı, the "Sunken Palace." It was built in the 6th century during the reign of Emperor Justinian I, at a time when Constantinople was thriving. The city’s booming population and growing palaces demanded a more reliable water supply, especially during sieges.
Tucked away in Istanbul’s Edirnekapı district, the Chora Church, today known as Kariye Mosque which is one of the finest surviving examples of Byzantine art and architecture. Originally built as a monastery church outside Constantinople’s city walls in the 4th century, it took its current form largely in the early 14th century, under the patronage of the powerful Byzantine statesman Theodore Metochites.
Just an hour’s ferry ride from the heart of Istanbul, Büyükada—the largest of the Princes’ Islands—offers a unique escape into history and nature. The island’s story begins as early as the 4th century, during the Byzantine era, when it became a place of exile for members of the imperial family. Princes, empresses, and patriarchs who fell out of favor were banished here, far from the intrigues of Constantinople. This somber legacy gave the islands their enduring name: the Princes’ Islands.
