Fethiye Mosque (Pammakaristos Church) – A Byzantine Treasure in Istanbul

Fethiye Mosque, originally known as the Pammakaristos Church, is one of the most important surviving Byzantine monuments in Istanbul. Located in the Fatih district, the structure reflects the city’s complex religious and cultural history.

Today, the building functions partly as a mosque and partly as a museum, preserving both its Byzantine heritage and Ottoman transformation.

The complex consists of two adjacent churches, one larger than the other, forming an architectural ensemble that dates back to the Byzantine period.

History of Pammakaristos Church

The original church of the Pammakaristos Monastery was built in the early 12th century during the reign of Byzantine Emperor John II Komnenos (1118–1143).

The construction was associated with the imperial family, including Anna Komnene, a prominent Byzantine historian and princess.

Later, between 1290 and 1294, the church was restored by Michael Glabas Tarchaneiotes, a high-ranking Byzantine military commander and relative of Emperor Michael VIII Palaiologos.

After the death of Michael Glabas, his wife Maria Doukaina commissioned the construction of a parecclesion (funerary chapel) in 1315. This smaller structure served as a burial chapel and contains the tombs of both Michael Glabas and Maria.

Conversion into Fethiye Mosque

After the Ottoman conquest of Constantinople, the building continued to serve religious functions.

In 1587, during the reign of Sultan Murad III, the church was converted into a mosque following Ottoman military victories in Georgia and Azerbaijan. The building was renamed Fethiye Mosque, meaning “Mosque of the Conquest.”

The structure underwent repairs during the mid-19th century (1845–1846).

Later restorations carried out between 1936 and 1938 transformed the smaller chapel into a museum, while the main building continued to function as a mosque.

Architecture of the Complex

The complex consists of two connected churches built side by side.

The main church follows the cross-in-square plan typical of middle Byzantine architecture.

The smaller chapel, known as the parecclesion, was added later and serves as a funerary structure.

The architectural layout of this chapel resembles the additional structures found in other famous Byzantine monuments such as Chora Church (Kariye).

Byzantine Mosaics

The museum section of the complex contains 14th-century Byzantine mosaics that are considered highly valuable examples of late Byzantine art.

Although only a few mosaics survive, they display remarkable artistic quality and provide insight into Byzantine religious imagery.

These mosaics depict sacred figures and decorative motifs typical of the Palaiologan Renaissance, the final flourishing of Byzantine art.
