Pammakaristos Church

Pammakaristos Church, also known as the Church of Theotokos Pammakaristos, is one of the most famous Greek Orthodox Byzantine churches in Istanbul, Turkey. Adapted in 1591 into the Fethiye Mosque, it is today partly a museum, the parekklesion. The edifice serves as one of the most important examples of Constantinople's Palaiologan architecture, and the last pre-Ottoman building to house the Ecumenical Patriarchate. It also has the largest amount of Byzantine mosaics in Istanbul after the Hagia Sophia and Chora Church.
