UNESCO Celebrates 50 Years of Protecting the World’s Natural and Cultural Sites

You may have been to a UNESCO World Heritage site in the United States or Canada without knowing it. Remember that Griswoldian summer vacation to the Grand Canyon?

The United Nations Educational, Scientific, and Cultural Organization, better known by the acronym UNESCO, was founded in 1945. Twenty-seven years later, on November 16, 1972, the organization’s World Heritage Convention rolled out a plan to protect the globe’s most valuable natural and cultural sites. In honor of the 50th anniversary of the milestone, UNESCO recently held a gathering in Delphi, Greece to discuss the next half-century of conservation and promotion of the essential properties.

Since 1978, when UNESCO anointed its first dozen, 1,154 attractions in 167 countries have earned the distinction. Of those, 897 are cultural, 218 are natural, and 39 are a hybrid of both categories. Italy boasts the most with 58 and several countries claim one such as Fiji, Mozambique, and the United Arab Emirates. The United States and Canada are in the middle of the pack.

Twenty-four sites are in the United States including Yellowstone National Park, Mesa Verde National Park, the Statue of Liberty, and various buildings showcasing the iconic architecture of Frank Lloyd Wright. Canada has 20 designated sites including Wood Buffalo National Park, the Canadian Rocky Mountain Parks, Historic District of Old Quebec, and Head-Smashed-in-Buffalo Jump.

The site also encompasses two acequia systems (irrigation ditches), laborers (farm fields), and Rancho de las Cabras, the estate in Floresville that supplied goats to Mission Espada.
