Choum ( ar, شوم) is a town in northern
Mauritania
Mauritania (; ar, موريتانيا, ', french: Mauritanie; Berber: ''Agawej'' or ''Cengit''; Pulaar: ''Moritani''; Wolof: ''Gànnaar''; Soninke:), officially the Islamic Republic of Mauritania ( ar, الجمهورية الإسلامية ...
, lying in the
Adrar Region close to the
border with
Western Sahara. In the year 2000, Choum had a population of 2,735.
History
The town grew from its position on
trans-Saharan trading routes. It declined with the trade, and, in 1977, was attacked by French troops as a suspected base of the
Polisario Front, the national
liberation movement fighting for independence for the Western Sahara. Fortifications from the period survive around the town.
Transport
Choum is a stop on the
Mauritania Railway from
Nouadhibou on the Atlantic coast to
Zouérat, and a transport interchange for access to the
Adrar Plateau and the Mauritanian capital
Nouakchott.
Railway tunnel

The town stands on a spur of land which carries the major turning-point in the border between Mauritania and the Western Sahara. In the early 1960s, the French colonial authorities in Mauritania wished to build the line from Nouadhibou to Zouérat to exploit the

, but imposed conditions unacceptable to the French.
The French engineers therefore built the line parallel with the border and tunneled through the Choum hillspur — two kilometres through solid
granite just to stay within French territory. The tunnel has been called a "monument to European stupidity in Africa".
The absurdity was highlighted when the southern part of the territory of Western Sahara was briefly administered by Mauritania after the Spanish withdrew in 1975/1976. The tunnel is no longer in use and a 5 km section of the railway cuts right through the
POLISARIO controlled part of the Western Sahara ().
The N1 highway from
Atar now runs all the way to north
Zouérat, but the sandy track paralleling the railway west to
Nouadhibou traverses low dune cordons so is much easier in a 4WD. Regular vehicles can be loaded onto a flatbed wagon at Choum.
