Susa, Palace of Artaxerxes II Mnemon
Susa (Elamitic, Babylonian: Šušim; Greek τὰ Σοῦσα): capital of Elam, favorite residence of the Persian king Darius I the Great.
In 1970, a farmer from Susa ploughing a field west of the river Shaour discovered the bases of several ancient Achaemenid columns. From an inscription, which became known as A2Sd, it is clear that the columns belonged to a palace built by king Artaxerxes II Mnemon (r.404-358). There was a paradise (i.e., a garden) next to it.
By the grace of Ahuramazda, I built this palace, which I have built in my lifetime as a pleasant retreat [paradise]. May Ahuramazda, Anahita, and Mithra protect me and my building against evil.
The roof of the hall rested on sixty-four wooden columns, which were painted blue. The walls were covered with red and blue plaster. The site appears to have remained in use until the Early Islamic period.
