Djémila is a mountain village in Algeria, near the northern coast east of Algiers, where some of the best preserved Berbero-Roman ruins in North Africa are found. It is situated in the region bordering the Constantinois and Petite Kabylie (Basse Kabylie).
In 1982, Djémila became a UNESCO World Heritage Site for its unique adaptation of Roman architecture to a mountain environment. Significant buildings in Djémila include a theatre, two fora, temples, basilicas, arches, streets, and houses. The exceptionally well preserved ruins surround the forum of the Harsh, a large paved square with an entry marked by a majestic arch.
