Hagia Sophia Grand Mosque (Ayasofya Kebir Camii) Istanbul
All of the doors have mythical stories of the origin of their wood.  These were covered in bronze.  The motifs are 6th century Byzantine interpretations of classical motifs like acanthus.  The Byzantines were famous for their bronze doors that were inlaid with gold and silver,  which were sent all over the Mediterranean. Clergy and monks from the West ordered sets of doors on visits to Constantinople directly from the makers.  A number of sets of these doors have survived.

The bars of the crosses on all of the doors have been removed after Hagia Sophia was converted into a mosque.  The rest of the ornament on the bottom panels has also disappeared.
