The United Nations Educational Scientific and Cultural Organization (UNESCO) undertakes to recognize, list, and collectively present those places around the world that are of outstanding value to all mankind and that must be protected from threads such as armed conflict, deliberate destruction, economic pressure, natural disasters, and climate change. Through the listing of such “world heritage sites,” UNESCO intends to document and protect the diversity of cultures and natural phenomena around the globe, and to promote international dialog. The sites may be classified as cultural or natural, or both, although most sites are cultural. As part of its listing, the UNESCO also includes short descriptions of each site. These descriptions are a key element in the public-facing listing of the recognized world heritage sites. The texts reflect the listing in a more nuanced and elaborate form (UNESCO 2021). As a literary genre, the site descriptions may fall somewhere between encyclopedia entries and travel-guide site descriptions, as they are intended both for matters of overview and as information for travelers. The UNESCO world heritage list was met with much success and was welcomed by broad audiences around the globe. Given the importance of the mission to promote international dialog, we have studied the world heritage site descriptions through a new method of geographical mapping (Baciu 2019, 2020, 2021). We were interested in exploring whether, through this new method, we can detect an international dialog, as promoted by UNESCO through the world heritage list and site descriptions. In this present essay, we discuss the results. UNESCO does promote an international dialog that we are able to detect using our method. The geographical connections that we detect are very close to other known global activity. We discuss in particu-lar the similarity between our mapping results obtained from texts published by UNESCO and global movement as decoded from airplane condensation trails (contrails). Both, text and air travel, reveal similar connection pathways across the globe, which suggests that text and air travel have evolved together rather than independently.
