Introduction to Berber Cave: The Berber cave architecture is a unique architectural form invented to adapt to the local geographical environment and climate. It can not only avoid the hot sun, but also prevent the wind and sand from blowing Attack. Because it's underground, you won't feel stuffy during the day and it's a little cool at night. There are many blue palm prints and fish-shaped patterns on the walls on both sides of the cave door. They are auspicious pictures to protect oneself and ward off evil spirits, and can bring good luck to people.
