Djémila is the Roman city of Cuicul, a UNESCO World Heritage Site about 50 km west of Sétif. It is, without exaggeration, one of the finest Roman ruins anywhere in the world — a complete city preserved to above-window-sill height in many places, with a forum, temples, a theatre, triumphal arches, and extraordinary mosaic floors. The onsite museum holds the mosaics removed from the site for protection.
The site is easily reached by taxi from Sétif. Allow a full day: at least two to three hours for the ruins themselves, plus the museum. The setting on a high ridge above mountain valleys is dramatic. Bring water and sun protection — there is little shade and the altitude makes the sun fierce even in mild weather.
