The HERITY Global Evaluation System (HGES) is designed to inform the public on the state-of-the-art of a site, a museum, monument, library or archive with regard to its perceived Value, Conservation status, Communication capabilities and Services, at the same time assisting those responsible to better manage the assets they are in charge of.
 

At present, the HERITY system makes it possible for cultural assets all over the world to be certified. In fact, the HGES allows specialists to better understand the variables which influence the three key-questions they normally have to face:
1. Avoiding low visitor numbers at Cultural Heritage sites;
2. Reducing the impact;
3. Managing the balance.
 

The main set of questions and problems to be answered came from the observation of visitor behaviour in Rome, as an example of an Art City characterized by cultural vestiges and activities as well as by significant tourism pressure.
