Palace of Blachernae

The Palace of Blachernae was an imperial Byzantine residence in the suburb of Blachernae, located in the northwestern section of Constantinople . The area of the palace is now mostly overbuilt, and only literary sources are available as to its description.

The Palace of Blachernae was constructed on the northern slopes of the Sixth Hill of the city in circa 500. The hill itself was partially remodelled, particularly in later times, and a number of terraces created to support the various buildings comprising the palace complex. Although the main imperial residence during the 4th–11th centuries was the Great Palace at the eastern end of the city, the Blachernae palace was used at times, and is attested in the ceremonial protocols contained in the 10th-century De Ceremoniis, or Explanation of the Order of the Palace, Chapters I.27, I.34, II.9, II.12) of Emperor Constantine VII Porphyrogennetos . At that time, it included several structures: the hall of Anastasius or Anastasiakos , named after Emperor Anastasius I who built it, the hall of the Ocean or Okeanos , the portico of Joseph or Iosephiakos , and the hall of the Danube or Danoubios . The latter communicated with the nearby shrine of the Greek Orthodox Church of St. Mary of Blachernae through a series of staircases.
