Where are the Pera Palace Hotel and Palace of the Porphyrogenitus located?
Palace of the Porphyrogenitus The Palace of the Porphyrogenitus (Greek: ), known in Turkish as the Tekfur Sarayı ("Palace of the Sovereign"), is a late 13th-century Byzantine palace in the north-western part of the old city of Constantinople (present-day Istanbul, Turkey). An annex of the greater palace complex of Blachernae, it is the best preserved of the three Byzantine palaces to survive in the city (together with the ruins of the Boukoleon Palace; and the ruins of the Great Palace of Constantinople with its surviving substructures, retrieved mosaics and standing Magnaura section), and one of the few relatively intact examples of late Byzantine secular architecture in the world.
