Today I have three American UNESCO sites, one new to my UNESCO collection.


First, the new UNESCO card! This card shows the Cahokia Mounds in Illinois. In the 11th century, Cahokia was a large city — one of the largest cities in the world. It was built and inhabited by the native peoples who were part of the Mississippian culture. The tallest mound at the site is Monk’s Mound, which is 100 feet (30 meters) high.

The  site was listed on the UNESCO list in 1982. The card was sent by Glisten on the Postcrossing forum.


The next card comes as an official Postcrossing card. It shows the Grand Canyon in Arizona, a UNESCO site since 1979.


And finally, another official Postcrossing card showing Independence Hall in Philadelphia, Pennsylvania. Independence Hall was the site where the the Declaration of Independence was signed, and where the Constitution of the United States was debated on and drafted. The Hall was also listed as a UNESCO site in 1979.

Interestingly, both of the official Postcrossing cards used the same stamp:

1963 March

This stamp was released in 2013 to commemorate the 1963 March on Washington, an important event during the Civil Rights Movement of the 1960s.


And Glisten used this new 2014 stamp depicting some stylized stars and stripes.
