This card is another gift from a postcrosser i met in Zurich, Verena "vre". It's my second card from Algeria.
"Ghardaïa is the capital city of Ghardaïa Province, Algeria. It is the traditional heart of the M'zab valley, home of the Ibadi sect in Algeria, and has preserved its original medieval architecture remarkably well; the valley of which it forms a part is an official World Heritage Site. Ghardaïa is renowned for its coarse goat hair carpets, generally with simple geometric patterns in black and white." - in: wikipedia
