I excavated at this site in 1990 and 1991 under the guidance of historian Dierk Lange and archaeologist Ade Obayemi of the National Monuments Commission of Nigeria. I is surely a very impressive site, with a relatively well preserved inner settlement structure,and dating from the late 15th (or early 16th century) to the late seventeenth or early 18th century. With Google MapPlanet any internet surfer can get an excellent impression of this highly visible site about sixty kilometers west from Sokoto not far from Gande near the village of Dargana (lat. 13.0848, lon. 4.8944).
