Meninx is a Tunisian archaeological site located on the south-east coast of the island of Djerba, near the present city of Henchir El Kantara. It stretches two kilometers long and eight hundred meters wide, some of which has probably been submerged by the sea.It is at 33° 40′ 59″ N, 10° 55′ 07″ E.
It was originally a trading post founded by the Phoenicians but reached its apogee in Roman times, when it became the chief town of the island, which was also called Meninx at the time. Meninx town was a major producer of priceless murex dye, and is cited by Pliny the Elder as second only to Tyre in this regard.
The first archaeologists to investigate the site highlighted thermal baths, an amphitheater, a theater, a basilica and probably a forum. Moreover, the ground was strewn with vestiges, such as bases of white marble columns, granite columns, capitals as well as numerous statues. In 1942, excavations were carried out by Paul-Marie Duval, though the site has not been thoroughly investigated to date.
