This year marks the 40th anniversary of the adoption of the United Nations Educational, Scientific and Cultural Organization World Heritage Convention. Over those 40 years, 189 countries have signed on to the Convention, making it perhaps the most nearly universal treaty for cultural preservation and nature conservation in human history.

In celebration of the Convention’s 40th anniversary, Eastern National and the National Park Service’s Office of International Affairs have produced the new booklet World Heritage Sites in the United States. The booklet highlights the 21 sites in the United States that have been selected and inscribed on the World Heritage List for their natural or cultural significance that makes them of outstanding universal value.

From Independence Hall to the cliff dwellings at Mesa Verde National Park, the booklet includes some of the United States’ most iconic sites and some lesser-known ones that have earned inclusion on the prestigious World Heritage List.

As part of Eastern National’s Passport To Your National Parks® program and the Passport Commemorative Series, this booklet includes a block on each page for visitors to get their booklet canceled with a Passport stamp that records the name of the site and the date of the visit. Cancellations are free and are usually available at a park’s visitor center.

“We are privileged to have a wealth of World Heritage sites designated in the United States,” said George Minnucci, chief executive officer of Eastern National. “We are thrilled to offer this publication as one of the only guides available to these hallowed sites, and hope that it encourages visitation and interest in the World heritage areas of the United States.”

The World Heritage Sites in the United States is available now for $4.95 on this website. For more information on this publication or the Passport To Your National Parks® program, please visit www.eParks.com or call 1-877-NAT-PARK (1-877-628-7275). Wholesale opportunities are available.
