Fruitful cooperation and sister city relations between cities of Lille, France and Nablus, Palestine has produced a number of projects and initiatives that were carried out for the benefit of local communities and partner institutions in both cities. In 2015, municipalities and universities of Nablus and Lille launched "Urban Planning and Cultural Heritage Project" for two areas in Lille and Nablus. Technical teams from both cities worked together on urban planning and preserving cultural heritage for selected areas. They exchanged experience and thoughts, and learned about each other's culture. This project is another success in the history of mutual cooperation, understanding and respect between Lille and Nablus
