Molla Zeyrek Mosque

Molla Zeyrek Mosque in Istanbul, Turkey, occupies the former Byzantine monastery Church of the Pantokrator, one of the most significant surviving examples of middle Byzantine ecclesiastical architecture from the twelfth century. Built originally by the empress Irene Komnene and her husband Emperor John II Komnenos, the complex comprised three connected churches, a hospital, a library, and an imperial mausoleum, making it one of the most ambitious religious foundations of the Byzantine capital. After the Ottoman conquest of Constantinople, the building was converted to a mosque and entrusted to the scholar Molla Zeyrek, after whom it and the surrounding neighbourhood are now named. The district of Zeyrek, on one of the seven hills of the old city overlooking the Golden Horn, remains one of the most atmospheric neighbourhoods of the old city, with its sloping streets, wooden Ottoman houses, and views across the water toward the skyline of the historic peninsula. The mosque itself is remarkable for the preservation of significant Byzantine architectural features, including the distinctive opus sectile floor in the main dome chamber, now covered by carpets for prayer. The building has undergone extensive restoration in recent decades, and its contemporary use as an active mosque places it in a category shared with Hagia Sophia and Kariye: Byzantine churches turned Ottoman mosques in whose continuing religious function lies a remarkable thread of historical continuity. The daily congregation is composed of residents of the surrounding Zeyrek neighbourhood. Friday prayers fill the hall. Visitors with an interest in Byzantine architecture and its Ottoman afterlife should prioritise this mosque in their itinerary, though respectful conduct is essential: modest dress, shoes removed at the threshold, hair covered for women, quiet behaviour throughout, and photography avoided during active prayer. The surrounding Zeyrek streets reward an unhurried walk both before and after a visit to the mosque. Wooden Ottoman houses on the slopes around the Zeyrek neighbourhood retain something of the atmosphere that would have surrounded the mosque for centuries, and careful restoration has preserved this historic streetscape.
