Passage:

The Berber, are a group of people indigenous to North Africa. In the Nalut district of the Tripolitania region, Ghadames, an oasis town is known as the “pearl of the desert”. It is one of the oldest pre-Saharan cities and a grand example of a traditional settlement. Flying over, I was surprised to see just houses and more houses. There didn’t seem to be any pathways or alleys. Puzzled I flew down to investigate. I found that each house is built in such a way that it hangs over the alleys creating an underground network of passages. The ground floor of the house is used to store supplies, the next floor is for the use of the family and the open-air
terraces are reserved for women. They were talking a language I did not understand. I later learnt it was Ghadam􀜽s, a Berber language.

Towards the end of the month, for three days the old city of Ghadames comes alive with feasting, singing and dancing. It happens at the end of the date harvest. When all the work is done, the people head to the city’s World Heritage-listed old quarter to eat dates and celebrate. The people of the old quarter moved out in the mid-1980s, and live in the modern town. But, on this occasion they return to their family homes in the old city. They throw open the doors for singing, dancing and other festivities. The covered alleys provide shelter from the hot Sahara sun.
