Algiers Observatory/Observatoire d'Alger (CRAAG)

The Algiers Observatory was built in the late nineteenth century in the Algiers suburb of Bouzaréah‎ . 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 . Le Centre de recherche en astronomie, astrophysique et géophysique, ou CRAAG, est un observatoire astronomique, connu autrefois comme l'Observatoire d'Alger. Il est créé en 1985, héritant de l'Observatoire astronomique de Bouzareah, construit en 1890, et de l'Institut de Physique du Globe d'Alger datant de 1931.
