Mohammed ash-Sheikh
The town Tagmadert was founded in 1550 by Mohammed ash-Sheikh. It was probably destroyed during the reign of Moulay Slimane (1792–1822), possibly like Sijilmassa in 1818 by Aït Atta Berber 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. Unfortunately there are no archeological records or Arabic or Berber language sources from which to deduce unequivocal conclusions about its location.
