Church of the Holy Apostles - Athens (Greece)

The Church of the Holy Apostles (Greek: Ἅγιοι Ἀπόστολοι, Turkish: Havariyyun Kilisesi), also known as the Imperial Polyándreion (Imperial Cemetery), was an Eastern Greek Orthodox church in Constantinople, capital of the Eastern Roman Empire. The first structure dates from the fourth century, although future emperors increase and improve space. It was the second in size and importance only for the Hagia Sophia among the great churches of the capital. When Constantinople fell in the Ottomans in 1453, the Holy Apostles became briefly the seat of the Ecumenical Patriarch of the Greek Orthodox Church. Three years later, the building, which was in a dilapidated state, was abandoned by the Patriarch, and in 1461 was demolished by the Ottomans to make room for the Fatih Mosque.
