SOUTHERN AND NORTHERN TETRAPYLS

These two aediculae formed by four arches supported by four pillars mark the crossroads of the Cardo with the Decumanus (perpendicular streets oriented east-west). Built in the 2nd century, the southern tetrapyle seems to have been surmounted by a pyramid and a statue, but only the bases remain. This crossing was redesigned at the end of the 3rd century to form a circular square lined with shops. The northern one was dedicated to Julia Domna, the Syrian wife of Emperor Septimius Severus (193-211). It consisted of four arches topped by a domed roof.
