Tasghîmût (also Tashgimut, Tashgimout) is a medieval fortress near Marrakesh, Morocco, built on a rocky plateau (an "erosion cirque") and fortified by the Almoravids under Ali ibn Yusuf in the 12th century to protect the nearby capital of Aghmat when the Almohads were making inroads in the western Maghreb. The fortress was conquered by the Almohads in 1132. Some archeological excavations were carried out in the 20th century, but many of the remains of the fortifications have been used for local building projects.
