Zellij ( Zellige in french ) is a 100% Moroccan art that has been passed down from one generation to another. It is Moroccan technique for surface coating that is more trendy than ever. What makes these tiles more interesting is the fact they are 100% man-made by only Moroccan hands. They can be found everywhere in Morocco, in addition to southern Spain ( Andalusia ) and the city of Tlemcen ( currently under the Algerian sovereignty ) that were both under the Moroccan reign for a few hundreds of years.
