Tagmadert (alsoTagumadert,Tagmad(d)art,Tigumedet) is a city in theDraa River valley inMorocco. The name seems to have referred to both a district and a town.
The town Tagmadert was founded in 1550 byMohammed ash-Sheikh. It was probably destroyed during the reign ofMoulay Slimane (1792–1822), possibly likeSijilmassa in 1818 byAït AttaBerber tribes. The present village of Amezrou may have been built on its ruins. A sequia (irrigation canal) called Tagmadert still exists today in that place.
