The United Nations World Tourism Organization defined Cultural Tourism as a category of tourism that helps tourists to learn about touristic landmarks and excavate their cultures, arts, literature, and history. It also sheds light on civilizations and their unique impacts on the world these days. With the world's increased focus on the preservation of archaeological sites and promoting architectural tourism, cultural tourism stands as the guardian of ancient civilizations and promoter of contemporary ones. One of the objectives of promoting cultural tourism and heritage preservation is to introduce a new understanding of certain cultures and their lifestyles, education, literature, and arts. These are factors that shape the essence of civilizations in the ancient world and the contemporary ages. It also aims to destroy the everlasting stereotypes about old or foreign civilizations.  Moreover, through focusing on the cultural aspects of civilizations, it is easier to discover new techniques of integration and promoting global dialogue. This has become crucial in the current circumstances where the world joins to face the threats of Covid 19. This resulted in open discussions on how to encourage sustainable tourism and eco-friendly environments. Therefore, IEREK is organizing the 4th edition of the international conference on Cultural Sustainable Tourism (CST2022) to help researchers discuss sustainable approaches to preserving the cultural heritage of countries across the globe. The conference also aims at creating a mutual understanding of the importance of green tourism through explaining civilizations' various techniques of spreading their cultures. The 4th edition of the conference is an integration opportunity to allow participants from different cultures and backgrounds to present their unique natures. From the comfort of you home, due to the global threat of Covid 19 and travel restrictions, you can participate in the discussions, attend the sessions, and present your research paper where it will be discussed by world experts and tourism enthusiasts.
