Tamanrasset was originally established as a military outpost to guard the trans-Saharan trade routes. Surrounded by the barren Sahara Desert, very high temperatures of over have been recorded here. Tamanrasset is located at an oasis where, despite the difficult climate, citrus fruits, apricots, dates, almonds, cereals, corn, and figs are grown. The Tuareg people were once the town's main inhabitants. Tamanrasset is a tourist attraction during the cooler months. Visitors are also drawn to the Museum of the Hoggar, which offers many exhibits depicting Tuareg life and culture.
