Major city of western Asia, in Khuzistan, Iran, with its first four phases paralleling those of Mesopotamia (Ubaid, Uruk, Jemdet Nasr, and Early Dynastic). It was the capital of Elam in Akkadian times (3rd, 2nd, 1st millennium BC) and again in the first as a capital of the Achaemenid empire. Susa controlled important east-west trade routes and was the end of the Achaemenid Royal Road from Lydian Sardis. Darius built the citadel c 500 BC. The tell is made up of four separate mounds: 1) the acropolis, which has produced most of the prehistoric material from the site; 2) the Royal City which has important Elamite remains of the 2nd millennium BC; 3) the Apadana, with a large, impressive Achaemenid palace; and 4) the Artisans' Town, of the Achaemenid period and later. It continued under the name of Seleucia after being captured by Alexander the Great in 331 BC; it later passed to the Parthians and Sassanians. Susa's characteristic fine ceramic ware had geometric motifs painted in dark colors onto a light background. Among the more important finds of Susa are the victory stela of Naram-Sin (Akkadian period), many Kassite kudurru, and the law code of Hammurabi (Old Babylonian period), which had been brought to Susa from Babylon after an Elamite raid. Susa was traditionally associated with Anshan (Tepe Malyan) in Fars.
