UNESCO stands for the United Nations Educational, Scientific and Cultural Organisation and was founded on 16 November 1945.
As of July 2017, there were a total of 1,073 World Heritage Sites. Of the 1,073 sites, 832 are cultural, 206 are natural and 35 are mixed properties.
As you can see Italy has 53 alone so I have just listed the natural World Heritage Sites below which will take you to the official website for all the information you need. They are organised alphabetically by country to help you see if there are any sites near your next holiday destination.
