Gemellae

Gemellae was a Roman fort and associated camp on the fringe of the Sahara Desert in what is today part of Algeria. It is now an archaeological site, 25 km south and 19 km west of Biskra, and 5 km southwest of the present-day village of M'Lili with which it probably shares an original Berber name. It was connected by military Roman road to Castellum Dimmidi and Capsa.
