Ouadane or Wādān () is a small town in the desert region of central Mauritania, situated on the southern edge of the Adrar Plateau, northeast of Chinguetti. The town was a staging post in the trans-Saharan trade and for caravans transporting slabs of salt from the mines at Idjil.
The old town, a World Heritage Site, though in ruins, is still substantially intact, while a small modern settlement lies outside its gate.
Ouadane is the closest town to the Richat Structure, a massive circular landmark visible from space.
The whole Ouadane commune has a total size of , mostly consisting of desert. The main town is located in the south-west of the commune.
The first written reference to the town is in Portuguese by Alvise Cadamosto in middle of the 15th century in a muddled account that confused the salt mines of Idjil with those of Taghaza.; ; At about the same date Gomes Eanes de Zurara described Ouadane as the most important town of the Adrar Plateau region and the only one with a surrounding wall.; Fifty years later Valentim Fernandes wrote a detailed account of the trade in slabs of salt from the Idjil mines and role of Ouadane as an entrepôt.; ; He described Ouadane as a 'town' with a population of 400 inhabitants.; . By contrast Duarte Pacheco Pereira in his Esmeraldo de situ orbis (written in 1505-1508) described the town as having approximately "300 hearths" which would suggest between 1,500 and 1,800 people.; The Idjil Sabkha lies roughly northwest of Ouadane, to the west of the town of Fderîck.The sebkha of Idjil extends 80 km north to south and 10 km east to west, . See the map in . The date when salt was first extracted from the sebkha is unknown. It is usually assumed that exploitation of the Idjil mines began after the mid 11th century as al-Bakri did not mention them. Instead he described a salt mine at a place that he called 'Tatantal'. Historians have usually assumed this corresponds to Tegahza but his description could possibly also apply to the mines at Idjil.
According to Pereira, in 1487 the Portuguese built an entrepôt in Ouadane in an attempt to gain access to the trans-Saharan gold, salt and slave trade. The entrepôt was probably short lived and is not mentioned in the detailed description provided by Fernandes.; ;
In the 16th century the Moroccans made various attempts to take control of the trans-Saharan trade in salt and especially that in gold from the Sudan. They organised military expeditions to occupy Ouadane in 1543-44 and again in 1584. Then in 1585 they occupied Taghaza and finally in 1591 their victory in the Battle of Tondibi led to the collapse of the Songhay Empire.
Tegherbeyat, the upper ruined section of the town, is almost certainly the oldest. It would have originally contained a mosque but nothing has survived. The ruins of the lower section of the town include a mosque that was probably built in the 15th century when the town expanded. Some of the are still standing and some walls still have the remains of clay plaster, suggesting that the mosque was abandoned sometime in the 19th century.. has a black and white photograph of the ruined mosque showing a round arch on page 223.
The mosque measured north–south at its eastern end and north–south at its western end where the minaret would have stood. From east to west it would have measured . The terrace was supported by five rows of horseshoe arches. At the eastern end are the remains of an external mirhab and a courtyard measuring that would have been used in hot weather.
