Timgad (called Thamugas or Tamugadi in old Berber) was a Roman colonial town in the Aurès Mountains of Algeria, 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, father Marcus Ulpius Traianus and his eldest sister Ulpia Marciana.
