Timgad

Timgad is the remains of a Roman colonial town in northeastern Algeria, founded around 100 CE by the emperor Trajan as a settlement for veterans. The site is notable for its unusually intact orthogonal street grid and surviving civic buildings, making it a key example of Roman town planning.

The main highlights include the straight decumanus and cardo axes that organize the town, the ceremonial Arch of Trajan, a large forum area, an open-air theatre and public baths. These elements give a clear sense of the town’s original layout and function as a planned military-colonial settlement.

Timgad was established under Roman imperial authority and developed through the 2nd and 3rd centuries CE; it later declined with changing political and economic conditions in late antiquity and the early medieval period. Excavation and conservation work in the 20th century exposed much of the street grid and major monuments still visible today.

The ruins lie in the Aurès region of northeastern Algeria in Batna Province, about 30 km east of the city of Batna and set on a plateau above surrounding agricultural land.

• Foundation: Founded around 100 CE as a Roman colony for veterans under the Emperor Trajan and laid out on a strict orthogonal grid.
• UNESCO: Inscribed as a UNESCO World Heritage Site for its exceptionally complete Roman town plan and surviving public monuments.
