Ksar el Barka (Arabic: كصر البركة, Fula: Laaci-Wendu) is a ruined town in Mauritania.
[2] Ksar el Barka is located approximately 50km north of Moudjeria in the Tammourt en Naaj, a basin that collects runoff from the Tagant Plateau into Lake Gabou.

[3]: 57 The Fula Jaawbe clan built their capital, Laaci-Wendu on the shores of Lake Gabou, a strategic location from which they could control the passes through the Assaba mountains.
