The Great Palace of Constantinople grew organically over centuries as the Byzantine imperial seat, expanding from Constantine's era through the Fourth Crusade. Only scattered fragments survive—a mosaic-filled parasyle court from Justinian's reign now preserved as the Great Palace Mosaic Museum, and the restored seaside Bukolian Palace facade. But most of this sprawling complex remains underground: the oldest Daphne Palace, the Golden Hall's octagonal domed chamber with its vast gilded table, and the legendary Magnaura where a famous steam-powered mechanical throne once stunned visiting ambassadors. Intermittent excavations near Hagia Sophia continue, but much stays unexplored.
