About Boukoleon Palace

Boukoleon Palace was an imperial Byzantine seaside palace located on the southern shore of the historic peninsula of Constantinople (modern Istanbul). It formed part of the coastal imperial complex and contained reception and residence spaces opening onto the sea.

Remains of the palace include sea-wall foundations and scattered masonry along the Marmara shore that indicate the palace’s former scale and its direct access to the water. The site lies close to other late antique and medieval monuments of the historic city.

The palace has origins in late antiquity and was expanded at different periods during the Byzantine era to serve imperial and ceremonial functions. It suffered damage and decline after the Latin occupation in the early 13th century and fell into disrepair under Ottoman rule.

The site sits on the Marmara-facing shore of Istanbul’s historic peninsula, near the site of the old imperial harbours and the city’s sea walls.

  • Seaside location: The palace stood on the Sea of Marmara shore of the historic Constantinople peninsula, forming part of the city’s imperial coastal palace circuit.

What to See#

  • Seafront complex ruins: The surviving sea-facing walls and foundations lie at the southern edge of the historic peninsula, adjacent to the medieval maritime installations of Constantinople.
