The Agora of Palmyra is part of a complex that also includes the tariff court and the triclinium, built in the second half of the first century AD. The agora is a massive 71 by 84 meters (233 by 276 ft) structure with 11 entrances. Inside the agora, 200 columnar bases that used to hold statues of prominent citizens were found. The inscriptions on the bases allowed an understanding of the order by which the statues were grouped; the eastern side was reserved for senators, the northern side for Palmyrene officials, the western side for soldiers and the southern side for caravan chiefs.
