Doukas (historian) in the context of "Eski Saray"

Eski Saray (Turkish for "Old Palace"), also known as Sarây-ı Atîk-i Âmire, was a palatial building in Constantinople under the Ottoman Empire in the Beyazıt neighborhood of the Fatih district, between the Süleymaniye Mosque and the Bayezid II Mosque.

Construction of the palace began shortly after the 1453 conquest and was completed in 1458. Historians of the period including Doukas and Michael Critobulus stated that it was completed in 1455.
