The
Algiers Observatory was built in the late 19th century in the
Algiers suburb of
Bouzaréah, Algeria, North Africa. It participated in the
Astrographic Catalogue project, taking the zone between -2 and +4 degrees to expose 1,260 plates between the years 1891 and 1911. At the tail end of that time, the director of the installation was
François Gonnessiat.
