Timgad (called Thamugas or Thamugadi in old Berber) was a Roman-Berber town in the Aurès Mountains of Algeria. It was founded by the Emperor Trajan around AD 100. The full name of the town was Colonia Marciana Ulpia Traiana Thamugadi. Trajan commemorated the city after his mother Marcia, eldest sister Ulpia Marciana, and father Marcus Ulpius Traianus.
