Historical Overview

Byzantine Origins

The site’s earliest phase dates to the 10th century, when it was constructed as an Eastern Orthodox church. Archaeological evidence points to a tripartite sanctuary, a crypt below the central apse, and domed side chapels. Frescoes depicting the Theotokos and Christ child, along with a Marian cycle, demonstrate the church’s artistic and religious significance (The Byzantine Legacy).

Genoese and Roman Catholic Era

Following the Ottoman conquest in 1453, the church was transferred to Christians from the Genoese colony of Caffa in 1475 and became Saint Mary of Constantinople, a Roman Catholic church. This era reflects the district’s complex religious landscape, with Christian communities maintaining a distinct presence until the mid-17th century (The Byzantine Legacy; DBpedia).

Ottoman Conversion

In 1640, Vizier Kemankeş Kara Mustafa Pasha converted the church into a mosque, initially named after him and later known as Odalar Câmîi (“mosque of the barracks”), referencing nearby Janissary barracks. Ottoman-era modifications included the addition of a mihrab, minbar, and minaret, although the minaret collapsed in the early 19th century (Wikipedia).

Architectural Features

Despite later changes, the core Byzantine elements—tripartite sanctuary, crypt, and domed chapels—remain identifiable. The masonry alternates between courses of brick and stone, with frescoes of saints such as Saint Mercurius, some of which are now preserved in the Istanbul Archaeological Museum. The site’s cross-in-square plan and domed structure are classic examples of middle Byzantine architecture (The Byzantine Legacy).

Decline and Current State

A devastating fire in 1919 left the mosque in ruins. Urban encroachment concealed much of the structure until recent demolitions revealed remnants of the original walls. Today, only fragments remain, largely unmarked and set amongst residential courtyards (Touristlink).
