The book “World Heritage of the Arab Countries” in its second edition, written in three languages (Arabic, English and French), aims to present and promote the World Heritage sites in the Arab world and disseminate information, which are sites that extend from the Maghreb to the Gulf and vary significantly between sites. The number of cultural and natural sites in the second book is 86, an increase of 20 sites compared to the first edition of the book. These new sites were inscribed on the World Heritage List between 2011 and 2019, reflecting the richness and beauty of the heritage found.
