What is a UNESCO World Heritage Site?
If you’ve read travel articles even occasionally, you’ve surely come across the term “UNESCO World Heritage Site.” For years, I kept seeing it pop up in guides, blogs, and itineraries, but I never stopped to ask the important questions: What exactly does this mean? Why should I care? And can I impress people at dinner parties by knowing random facts about it? (Spoiler: Yes, you can.) So, I decided to do some digging into what it really takes for a place to earn that illustrious UNESCO badge of honor.

The Acronym: A Fancy Way of Saying Something Important

UNESCO stands for the United Nations Educational, Scientific and Cultural Organization. The group was founded in 1945, initially to reconstruct Europe’s educational systems after World War II. It was a noble mission, but nine years later, things got even more ambitious when Egypt’s Aswan Dam project threatened to flood ancient Egyptian treasures. UNESCO stepped in, organized a worldwide safeguarding campaign, and thus began its crusade to protect and conserve sites of outstanding cultural and natural significance. Think of UNESCO as the superhero of landmarks—cape not included.
What Makes the Cut?

To be named a UNESCO World Heritage Site, a place has to be of “outstanding universal value” and meet at least one of ten stringent criteria. These criteria range from representing a masterpiece of human creative genius (looking at you, Taj Mahal) to containing superlative natural phenomena (hello, Grand Canyon). The full list includes both cultural and natural wonders, and some places—like Machu Picchu—even check both boxes.
A few criteria highlights:
- Human creative genius: You know, like Michelangelo-level stuff.
- Exceptional testimony to a cultural tradition: Think ancient cities or iconic temples.
- Superlative natural phenomena: Basically, anything that makes you gasp and say, “This doesn’t even look real!”
Fun fact: There are currently 1,199 UNESCO World Heritage Sites scattered across 167 countries. So, if your goal is to see them all, I hope you’ve got a lifetime, a trust fund, and a really good suitcase.
A Global Safeguard

One particularly cool thing about UNESCO World Heritage Sites is that they’re legally protected under the Law of War, per the Geneva Convention. This means acts of hostility against these sites are prohibited. Of course, this doesn’t always stop destruction—tragically, the Buddhas of Bamiyan in Afghanistan were destroyed by the Taliban in 2001 despite international outcry—but it’s a step in the right direction.
Why Should You Care?

For starters, visiting UNESCO sites is like stepping into the pages of a living history book. These places aren’t just old; they’re significant. They tell stories of ancient civilizations, awe-inspiring natural forces, and cultural traditions that shaped the world as we know it. Plus, let’s be honest, they make for incredible Instagram photos.
For example, this summer my kids and I will be exploring Spain and Portugal, where we’ll visit no fewer than seven UNESCO sites. From the stunning Alhambra in Granada to the fairytale-like town of Sintra in Portugal, these landmarks promise to be unforgettable—even to my teens, who will likely be half-glued to their phones the whole time. (Pro tip: “This is a UNESCO site” is a surprisingly effective way to get a kid to look up. Briefly.)

Preserving the Past for the Future

I’m grateful that UNESCO exists to preserve these treasures for my kids and all future generations. In a world where landmarks can fall victim to war, development, and neglect, it’s comforting to know that someone’s out there fighting the good fight. So next time you’re planning a trip, consider adding a UNESCO World Heritage Site to your itinerary. They’re not just destinations; they’re reminders of what humanity can achieve when we create, preserve, and protect.
