For most of us, when we hear of a United Nations World Heritage (UNESCO) site, we mistakenly think they’re all overseas.
Surprisingly, there are many UNESCO sites located in the United States.
There’s the Waterton-Glacier International Peace Park, which actually spans the border between Montana and Canada. It’s the world’s first bi-national peace park.
Mammoth Cave National Park in Kentucky was actually designated a UNESCO site back in 1981, and we’re talking over 400 miles of caves.
Another UNESCO site is the Cahokia Mounds State Historic Site in Illinois. It’s the largest pre-Columbian settlement north of Mexico. And at one point, the Cahokia settlement was larger than London.
