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.

Grand Canyon National Park © Rex Vogel, all rights reserved

Grand Canyon National Park

Est. 1979 | Arizona

Why it’s UNESCO-worthy: At 18 miles wide and a mile deep the Grand Canyon is a history book writ in rock. Its geologic layers tell a tale that goes back more than 1.8 billion years including the period 6 million years ago when the Colorado River first raised its carving knives.

San Antonio Missions © Rex Vogel, all rights reserved

San Antonio Missions

Est. 2015 | Texas

Why it’s UNESCO-worthy: In the early 1700s, Franciscan priests built Mission San Antonio de Valero (the Alamo), their first, to help Spain and the Catholic Church colonize, convert, and defend New Spain. Over the next 13 years, four more missions (Concepcion, San Juan, San Jose and Espada) sprouted up along a 10-mile stretch of the San Antonio River. The missions stir up the melting pot of influences from the colonial settlers, nomadic Coahuiltecans, and other indigenous hunter-and-gatherer groups who were integral to the early Texas settlement. 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.

San Antonio Missions © Rex Vogel, all rights reserved

How to reach it: The Alamo squats in the center of San Antonio; the other four missions are spaced about 2½ miles apart along Mission Road. Visitors can also access the sites by bike or foot on the Mission Hike and Bike Trail or partially by kayak on the San Antonio River.

Plan Your Travels around a UNESCO World Heritage Site

Discover these UNESCO heritage sites on your next RV road trip

Even if you’ve explored Everglades National Park in Florida and caught glimpses of alligators, manatees, and other wildlife, or visited Independence Hall in Philadelphia where important chapters in the birth of the United States were written, did you know that they’re among 24 places throughout America honored as World Heritage Sites by the United Nations Educational, Scientific and Cultural Organization?

And, there are 20 World Heritage Sites in Canada and each one is special in its own way.

Mesa Verde National Park © Rex Vogel, all rights reserved

UNESCO designates natural destinations and cultural attractions that are “of outstanding universal value” and meet one or more of 10 criteria. Among these are to exhibit “exceptional natural beauty,” provide habitats for threatened species, and be associated with events of “universal significance.”

Among diverse places on the list are East Africa’s Serengeti region, Australia’s Great Barrier Reef, the pyramids of Egypt, and great castles and cathedrals throughout Europe.

Mission San Juan (San Antonio Missions) © Rex Vogel, all rights reserved

UNESCO sites in the United States and Canada are equally varied. They range from alluring mountain parks to an ancient pueblo, from architectural treasures to cultural icons. You might like to use them as a wish list of places to visit in the future.

Great Smoky Mountains National Park © Rex Vogel, all rights reserved

It’s no surprise that Everglades National Park is included on the UNESCO list. It’s the largest tropical wetlands and forest wilderness in the country, the biggest mangrove ecosystem in the Western Hemisphere, and the most significant breeding ground for tropical wading birds in North America. It’s also home to 36 threatened or protected species.

One massive chamber, almost 4,000 feet long, is called the Big Room. Among names given to other caves are Kings Palace, Papoose Room, and Hall of the White Giant. The hundreds of thousands of bats that live in the caverns emerge around sunset to seek their evening meal. It’s also home to a section of the Capitan Reef, one of the world’s best-preserved and most accessible fossilized reefs.

Mesa Verde National Park © Rex Vogel, all rights reserved

The Pueblo people definitely left their mark on the American West, and their way of life remains intact at sites like Mesa Verde. The region is chalk full of thousands of archaeological sites including 600 cliff dwellings dating back to the 5th century. Carved into cliffs sitting 8,500 feet above sea level and surrounded by inhospitable desert landscapes, the tenacity and ingenuity of these ancient people is undeniable.

The park entrance is about 45 minutes from Durango and the best time to see Mesa Verde is May through October when some of the dwellings allow the public to visit. Check out the tons of petroglyphs all along the Petroglyph Point Trail.

The Alamo © Rex Vogel, all rights reserved

On your visit to Texas, expect to see a lot of missions—they’re everywhere, especially in San Antonio. First up was Mission San Antonio de Valero, also known as the Alamo which Franciscan priests built to help Spain and the Catholic Church colonize, convert, and defend New Spain. Over the next 13 years, four more missions were built along a 10-mile stretch of the San Antonio River, and together they make up an impressive UNESCO site.

Mission San José © Rex Vogel, all rights reserved

The Alamo is impressive, but if you want to see the best mission, check out the “queen” of all the San Antonio Missions—Mission San José. Once the heart of a vibrant Spanish community founded in the early 18th century, San José attracted people from all over the area. The church was built in 1768 and is still standing today.

Mesa Verde National Park: 14 Centuries of History

Mesa Verde offers a spectacular look into the lives of the Ancestral Pueblo people

Most of the national parks in the Southwest are about the landscapes, but Mesa Verde in southern Colorado is more cultural than natural.

There’s still plenty of rugged scenery, but there are also more than 4,000 archaeological sites contained within Mesa Verde’s boundaries.

Mesa Verde National Park © Rex Vogel, all rights reserved

Mesa Verde, Spanish for “green table”, offers a spectacular look into the lives of the Ancestral Pueblo people who made it their home for over 700 years, from AD 600 to 1300. Today the park protects these sites, some of the most notable and best preserved in the U.S.

Mesa Verde National Park © Rex Vogel, all rights reserved

Fourteen centuries of history are displayed at Mesa Verde National Park, 10 miles east of Cortez off U.S. Highway 160. More than 4,000 archaeological sites have been preserved, including hundreds of homes and villages that date back to the 12th century.

Mesa Verde National Park © Rex Vogel, all rights reserved

These master builders constructed elaborate complexes tucked into sandstone cliffs. Some held just a few people, while others, such as the Cliff Palace and Long House, have 150 rooms and could have housed up to 100 people.

Mesa Verde National Park © Rex Vogel, all rights reserved

Mesa Verde is a World Cultural Heritage Park, a designation granted by UNESCO to preserve and protect the cultural and national heritage of certain international sites. Mesa Verde has also been selected the number one historic monument in the world by readers of Condé Nast Traveler, and was chosen by National Geographic Traveler as one of the “50 places of a Lifetime—The World’s Greatest Destinations.”

Mesa Verde National Park © Rex Vogel, all rights reserved

Mesa Verde does not lend itself to a hurry-up visit. To truly appreciate the park and to visit several of the cliff dwellings, plan to spend a minimum of two days at the park. It takes time to savor the magic of its eight centuries of prehistoric Indian culture. As a vintage slogan at the park advises: “It’s a place where you can see for 100 miles and look back in time 1,000 years.”

Mesa Verde National Park © Rex Vogel, all rights reserved

The intricate architecture is as awesome to behold today as it was when cowboys and ranchers first saw it. Two men looking for lost cattle, Richard Wetherill and Charles Mason, came upon the most spectacular site, the 150-room Cliff Palace, in 1888. Mesa Verde was designated as a national monument by President Theodore Roosevelt 18 years later, in 1906.

Mesa Verde National Park © Rex Vogel, all rights reserved

From Mesa Verde’s entrance a two-lane paved road winds upward 2,000 feet through piñon-juniper forests and canyons. At Park Point, on the northern edge of the mesa at 8,600 feet, the visitor is treated to a panoramic view of the Montezuma Valley to the west, and the Mancos Valley, framed by the 14,000-foot San Juan and La Plata mountains to the east.

Mesa Verde National Park © Rex Vogel, all rights reserved

At Far View, the road divides. The west fork leads to Wetherill Mesa and a number of major cliff dwellings, including Long House, second largest at Mesa Verde. The south fork leads to Park Headquarters on lower Chapin Mesa and the major cliff dwellings of Cliff Palace, largest in the park, Spruce Tree House (closed to the public), Balcony House, Square Tower House, and others.

Mesa Verde National Park © Rex Vogel, all rights reserved

Spruce Tree House is the best preserved cliff dwelling in the park, but falling rocks from a sandstone overhang have kept the more than 700-year-old structure closed since October 2015.

Due to the complexity of the project and the significance of Spruce Tree House cliff dwelling, there is a four-phase sequential approach planned.

Mesa Verde National Park © Rex Vogel, all rights reserved

In early 2017, the park service contracted with a geotechnical firm to conduct Phases One and Two. This assessment will result in recommendations for treatment that, if necessary, will use modern engineering technology to ensure that the alcove is stable and safe for public visitation.

Currently, Spruce Tree House can be seen from overlooks near the Chapin Mesa Archeological Museum

Mesa Verde National Park © Rex Vogel, all rights reserved

Mesa Verde offers great camping just 4 miles inside the park at Morefield Campground. Because there are 267 sites, there’s always plenty of space. The campground rarely fills. But if you want one of the 15 full-hookup sites, reservations are a must.

Mesa Verde is open year-round, but actual schedules vary with the season. The campground and some sites are closed during the winter. The current entry fee to visit Mesa Verde National Park is $15-25 (fee is good for 7 days); all federal lands passes are accepted.

Worth Pondering

(The cowboys’ discovery of Cliff Palace) was the beginning of the mystery which is still a mystery. Who were these people, where did they go, and why?
