ALG-370. Home Arch is located on the maze of North Idou -Pronouced Idoo- site on the huge Tassili National Park, wilaya of Illizi, Algeria. The opening has a measured span of 13.2 meters and a height of 2.3 meters. Natural arches on Tassili-n-Ajjer (Ajjer Plateau) do not have official names. The author used names to help him memorize each formation, but these are not official names, just nicknames. Some arch names are from a word in the Targuia (Tuareg) dialect. In this case, the nickname  was given because the arch has evidence of human occupancy from the last century (not from prehistoric times).
