Today, they preserve vestiges of a rich medieval past.Throughout Oualata, doors fashioned from acacia wood, adorned with traditional designs painted by local women, punctuate the earthen facades. Family libraries safeguard centuries-old manuscripts, invaluable records of cultural and literary heritage passed down through generations.Yet, Oualata’s proximity to the Malian border leaves it acutely vulnerable to the unforgiving environment of the Sahara.
