The Municipality of Udine, which joint the "Healthy Cities" Project in 1995, is strongly committed on the theme of Healthy and Active Ageing since 9 years. In such a long period the staff and the experts involved acquired a clear vision of the processes, conditions and actors needed to achieve the results described above. By working within the WHO Network of Healthy Cities, Udine has developed a number of guides and manuals which are useful tools both to describe the good practice and to help receiving cities in transferring it.
