Fenari lsa Camii formely was the Monastery of Constantine Lips, a monastic complex composed of the Church of the Theotokos Panachrantos (the Immaculate Mother of God) built in 908 by Constantine Lips, a high official in the service of Leo Vl the Wise (886-912) and later of Constantine VII Porphyrogenitus. South of this church, the Church of St. John the Baptist also called St. John the Prodrome , and a small funerary chapel which were added in the late 13th century by Theodora, spouse of Michael Vlll Palaeologus (1261-1282). This imperial convent for ladies sheltered numerous tombs, including those of the Empress Theodora herself and of her daughter Eudocia. The churches were turned into a mosque in the late 15 th century. After the fire in 1622 which severely damaged the complex, the columns were removed and replaced by large pointed arches, and the roof and the two domes were reconstructed. The buildings were damaged again by the fire in 1917 and remained for many years in a neglected state.

The restoration work has highlighted the elaborate brick and ashlar decoration in the east side of the churhes, the fragments of mosaics and the inscription on a golden background related to Theodora, in the Church of St. John the Prodrome. Fenari lsa Camii is located in Fatih on the Adnan Menderes Bulvarı.
