Turkey, Istambul, St Sophia: was built by Justinian to replace an earlier basilica, destroyed in 532. He entrusted the task to Anthemius of Tralles and Isidore of Miletus, and placed enormous funds at their disposal. The work was completed within the astonishingly short space of five years and six months (532-537). Preceded by a huge narthex, the church proper occupies an area of 7000 square metres, being 77 long by 71,7 metres broad. The existing dome, rebuilt in 562, rises 54 metres above the ground with a diameter of 31 metres, surpassing in height that of the Panteon at Rome (43 metres) and the vaults of Gothic cathedrals. Today the floor is covered with great marble flagstones. In the time of Justinian, the Great Church was adorned with a pavement of mosaics combined with polychrome marbles, a description of which has come down to us. The lower portion of the walls was ornamented with marble facings, carefully polished. Above these marbles, the walls, vaults, dome and pendentives were decorated entirely with mosaics. These were either destroyed or covered with plaster when the church was converted into a mosque in 1453. The Byzantine Institute of America has removed the plaster and restored a large number of mosaics from the time of Justinian, but most of the mosaics are of post-iconoclastic date, between the middle of the 9th and end of the 12th centuries. It is possible that other mosaics survived in the dome, beneath the Turkish repaint. St Sophia was used as a mosque until 1935. Today it is a museum. St Irene: was one of the first sanctuaries in Constantinople. Rebuilt by Justinian in 546. Nothing survives of its decoration, apart from a large cross in the Eastern apse, which must have been executed in the iconoclastic period. St Theodore (Kilise Djami) mosaics of the 14th century; Chora Monastery (Kahrie Djami): mosaics and frescoes of 14th century.

The south nave of the church terminates in a lateral chapel decorated with important early 14th century mosaics. The Byzantine Institute of the University of Boston brought to light a Deesis and several mosaics, whose style recalls that of the Chora Church. St John of Studius, the Monastery of Studius was the largest in Constantinople and for centuries played a decisive role in the religious life of the Orthodox world. The monastic church – one of the most beautiful churches in the capital – is now a ruin. It is known that the walls were once decorated with mosaics, and there are still remnants of a fine mosaic pavement. http://en.wikipedia.org/wiki/Hagia_Sophia
Turkey, Cappadocia. The territory of Asia Minor whose capital was Caesarea. In the fifth and sixth centuries an important monastic colony became established in the volcanic region.

Trebizond (Trebzon, Trapezus). Capital of the Byzantine Empire between 1204-1461 and one of the main intellectual centres of Hellenism. Among the numerous churches of Trebizond may be mentioned St Sophia, the best preserved of the Byzantine monuments in Trebizond; probably built shortly after the accession of the Comnene dynasty of Trebizond in 1204. Enlarged and ornamented with frescoes in about 1260. These frescoes rank among the finest works of 13th century Byzantine painting.
