Jedars (French spelling: Djedars) is the modern archaeological name given to thirteen monumental Berber mausoleums south of Tiaret city in Algeria. The name is derived from the Arabic: جدار jidār (wall) which is used locally to refer to ancient ruins. These pre-Islamic tombs date from Late Antiquity (4th-7th? centuries CE).
The tombs are situated on the tops of two hills in the mountainous Frenda area, around 30 km south of Tiaret. There are three sepulchres on Jabal Lakhdar (35°06′47″N 1°12′45″E / 35.113098°N 1.212475°E), and ten on Jabal Arawi (35°03′48″N 1°11′01″E / 35.063391°N 1.183733°E, also known as Ternaten) 6 km south of the first group. The graves' size and commanding situation indicate that they were built for royalty. They have been systematically plundered for many centuries, and hence are in a state of ruin.
The monuments were erected straight onto the substratum or with very shallow excavation. Some stone was quarried from local limestone and sandstone, some was recycled from nearby settlements and necropoli of earlier times. The materials vary widely: dressed stone blocks 1-1.5 m. long, partially dressed blocks up to 2.4 m. long, natural rock slabs with minimal dressing, old tombstones, and old building fragments. Most of the construction is dry stone, lime mortar is used sparingly.
