Darius I built the palace complex at Susa known as the Palace of Darius.
Construction at Susa formed part of Darius’s major building program across the Achaemenid Empire. Susa was an important administrative and royal center, and its palace included monumental rooms, courtyards, decorated walls, and facilities for court ceremonies.
Excavations revealed glazed brick decoration featuring processions of soldiers and other figures. The famous “frieze of the Immortals” from Susa is now associated with the palace’s artistic program and is displayed largely in the Louvre.
Darius’s successors continued work at Susa, so the complex was not the product of one reign alone. Xerxes and later Achaemenid kings added or modified buildings. Susa therefore illustrates both Darius’s foundation work and the continuing development of a royal capital.
