Its ruins are called Aïn Tounga, southwest of Testour, Tunisia. They are very extensive and cover the summit and slopes of a series of hills. One inscription calls the town "Civitas Thignicensis" (the city of Thignica) and states that it was divided into three parts, another that it became a municipium at the beginning of the 3rd century under the name of "municipium Septimium Aurelium Antoninianum Herculeum Frugiferum Thignica". Towards the centre of the ruins is a Byzantine fortress, trapezoidal in shape, flanked by five square towers. Here an inscription makes mention of the proconsul Domitius Zenophilus (326-32), famous in the annals of Christian Africa. Among the other ruins are a small triumphal arch, a temple, a Christian church, the remains of the enclosure, etc.
