ALGERIA-HERITAGE-ARCHAEOLOGY

Experts and students from Algiers Universitys Archaeology Institute work on one of the Jeddars pyramid tombs, near the city of Tiaret, some 340 kilometres (210 miles) southwest of the Algerian capital, on April 23, 2018. - Dating back up to 16 centuries, Algeria's Jeddars pyramid tombs are unique relics of an ancient era, but a dearth in research has left them shrouded in mystery. Constructed between the fourth and seventh centuries, the tombs are believed by some scholars to have been built as final resting places for Berber royalty.
