Throughout history, cities have been looked upon, and sought, as places of protection, as fortresses whose walls shielded its residents from foreign invasions or feudal wars. Over centuries, urban dwellings have built up their status as depositories of knowledge and hubs of cultural traditions to become centres of excellence for arts and sciences, and a source of creativity and innovation. Today, urban settlements, towns and cities are playing a key role as generators of ideas, catalysts for change and a tool for pooling resources to advance development in a more sustainable manner.
