The inscription of a cultural site on UNESCO's World Heritage List is not an end in itself. The characteristics and the qualities that justified its inscription must be preserved. While it is the responsibility of the international community and local officials, it is also the responsibility of each and every one of us to help safeguard the cultural and natural sites of the earth before it is too late.

It is a question of protecting the heritage to pass it on to future generations, to make it accessible to a greater number of people, and also to ensure that this heritage, an essential component of cultural diversity, is developed properly.

One of the key objectives of the OWHC is to favour, both on the regional and international levels, cooperation and the exchange of information and knowledge between World Heritage cities. In that sense, the OWHC organized the " City2City " program that is intended to disseminate all types of exchanges and dialogues among its member cities.



City2City (C2C) is a program intended to provide practical assistance to the cities that are members of the Organization and that have specific challenges or difficulties related to the management of world heritage. In particular:

  • Techniques in preserving;
  • Innovation and enhancement;
  • Management and planning;
  • Awareness and public communication;
  • Etc.

The primary mandate of the C2C program is to allow for the networking of various member cities of the OWHC:

  • The applicant – the city that is a member in good standing of the OWHC and that is looking for expertise in order to solve a specific problem related to its world heritage;  
  • The respondent – a member in good standing of the OWHC having the experience, the knowledge and/or the managers that can meet the needs of the applicant.      

C2C however proposes three different avenues to respond to an applicant:

  1. A database making it possible to have access to the scientific contents developed by/for/in collaboration with the OWHC for various activities.  
  2. A call for expertise through the network of the OWHC, in addition to bringing the applicant and the respondent into contact;
  3. An application for networking – financial assistance in order to allow the respondent to make a contribution on the ground, with the applicant, in addition to international communications throughout the network of the OWHC.


  • To meet the specific needs of a city that is a member in good standing of the OWHC;
  • To foster cooperation;
  • To disseminate knowledge;
  • To raise awareness among the public and the networks of the OWHC of different challenges of world heritage.  


  • Any city that is a member in good standing of the OWHC for the last three years may be an applicant.
  • Any city may be an expert.
  • The database is open to the public.


The database, which is open to the public, makes it possible to consult the expertise and the knowledge of various world heritage cities owing to projects they realized and which are listed in it. 

Many cases that constitute the database contain the names and contact information of the persons in charge of the project. Thus, it is possible to take the steps required in order to obtain additional information.   


The applicant must submit a complete candidacy file.

In the case of a call for expertise, the OWHC undertakes only to act as a liaison officer, that is, once the candidacy file is submitted, it will be disseminated through the Organization’s network. Thereafter, if a respondent answers the applicant’s request, the OWHC will put them in touch.

Concerning the calls for expertise, the OWHC will consider itself a priori as being excluded from them.  

If the applicant and the respondent wish, they may submit an application for networking.  


If the applicant wishes to have a representative for assistance on the field, the OWHC can provide support.  

Further to an application for networking, the applicant and the respondent accept to comply with the tripartite agreement. The tripartite agreement is the opportunity to clearly define the roles expected from the applicant and from the respondent. An agreement proposal is available – see the document – Tripartite Networking Agreement.
