Timgad

Timgad was founded by Roman Emperor Trajan around 100 CE. It was established as a veterans' colony to provide retired Roman legionaries with land. The settlement was situated in the Aurès Mountains of modern-day Algeria.

The city is a prime example of Roman urban planning, featuring a strict orthogonal grid plan modeled exactly after a Roman military camp. This "checkerboard" layout is exceptionally well-preserved and visible in the ruins today. Its design lacked the organic, winding streets typical of older North African settlements.

Among its most notable monuments are the Trajan Arch, a large theater, and extensive public baths. The site also features a well-preserved public library, which is a rare find in Roman archaeology. Visitors can easily spot the marks of ancient chariot wheels still worn into the stone-paved streets.

The city declined after being sacked by the Vandals in the 5th century and later suffered from Berber raids. It was eventually abandoned, and the ruins were gradually buried by Saharan sand. The site remained lost until French explorers and archaeologists excavated the area in the late 19th century.
