The Palace of Blachernae (Greek: τὸ ἐν Βλαχέρναις Παλάτιον)[1] was an imperial Roman residence in the suburb of Blachernae, located in the northwestern section of Constantinople (today located in the quarter of Ayvansaray in Fatih, Istanbul, Turkey). The area of the palace is now mostly overbuilt, and only literary sources are available as to its description.
