Arch of Trajan (Timgad)

The Arch of Trajan is a Roman triumphal arch located in the ancient colonia of Timgad in modern-day Algeria. The arch dates back to the 2nd century or the beginning of the 3rd century. The three-arched structure was used as the western gate of the city at the beginning of the decumanus maximus and the end of the road coming from Lambaesis.

The arch has a height of 12 m, with the central span being 6 m in height while the two smaller arches on each side are 3,7 m in height. The arch stands among the ruins of the ancient city of Timgad. The whole site is listed as a UNESCO World Heritage Site.
