This study of the fortunes of the Mosque of Cordoba at the hands of the Neo-Moorish architects of the late 19th and early 20th centuries proposes a journey through forms that originate at the Columbian Exposition in Chicago in 1893 and take root to some extent in Havana, Lima and, ultimately, in Chile. The importance of this phenomenon of historicist reinterpretation, the subject of less research than the omnipresence of alhambrismo, is highlighted. Finally, unpublished data and graphic material on the subject of Chilean Neo-Moorish structures, which never been analysed or only sparingly so, is revealed.
