Everything You Wanted to Know About UNESCO World Heritage Sites But Never Bothered To Ask

UNESCO World Heritage Logo

As you may have noticed, I have a slight fetish about visiting world heritage sites. To date I have visited over 375 of sites and I have made a point of featuring each one I visit as a daily photo. Some of them are incredible and some are……less than incredible.

I’ve had several people ask me what the deal was and why I bother to go out of my way to visit them. If you have traveled even a small amount there is a good chance you have already visit one or more sites without even knowing it. There is also a good chance you’ve been near one and never bothered to take the time to go and visit it.

This post is intended to be a primer for what World Heritage Sites are about, why they exist and why you should consider making them a part of your next trip.

World Heritage Background

If you were to sit down and come up with a list of the great places in the world that people should visit, I would bet that almost everything on that list, if it is natural or historic, would be a world heritage site. I’ve often described world heritage sites as the Hall of Fame for national parks

Abu Simbel
The UNESCO preserved monument at Abu Simbel

UNESCO stands for the United Nations Educational, Scientific and Cultural Organization. The first mission which UNESCO undertook to preserve a cultural property took place in 1954 when they raised money from member states to move the Abu Simbel and Philae Temples in Egypt from the flooding of the Aswan High Dam. They literally took the temples apart piece by piece and put them together several hundred meters away on higher, dry ground.

The creation of a formal organization to protect the world’s cultural and natural heritage began in 1965 when the Johnson Administration hosted a conference for the creation of a “World Heritage Trust”. This lead to the the Convention Concerning the Protection of the World Cultural and Natural Heritage which was passed by UNESCO in 1972 and the creation of the World Heritage Committee in 1976.

The first sites were inscribed to the World Heritage list at a session of the World Heritage Committee in 1978 in Washington DC. 12 sites were listed at the first conference in 1978:

As of 2019, there are 1,092 World Heritage Sites located in 153 countries. They consist of 814 cultural sites, 203 natural sites, and 35 mixed sites.

How Something Becomes a World Heritage Site

The process of becoming a world heritage site can be long and very political.

Each country which is part to the World Heritage Convention can place sites in their country to the tentative list. Only sites on the tentative list can be nominated at the annual convention to be placed on the list. To give you an idea, here are the sites which the United States has placed on their tentative list (as of 2011):

White Sands National Monument. NOT a world heritage site.
  • Civil Rights Movement Sites
  • Dayton Aviation Sites
  • Hopewell Ceremonial Earthworks
  • Thomas Jefferson Buildings
  • Mount Vernon
  • Poverty Point State Historic Site
  • San Antonio Franciscan Missions
  • Serpent Mound
  • Frank Lloyd Wright Buildings
  • Fagatele Bay National Marine Sanctuary
  • Okefenokee National Wildlife Refuge
  • Petrified Forest National Park
  • White Sands National Monument
The ruins of Angkor

Many people confuse the tentative list with the actual heritage site list. I had a discussion with someone in Alabama who insisted that the Civil Rights Movement Sites were world heritage sites. They are not. They might be at some future time, but as of now, they are only proposed.

Getting sites actually on the list involves a lot of horse trading. If you look at which sites are added each year you’ll notice very small countries which seem to get sites every year. I can’t help but think that is part of some sort of quid pro quo voting which has been done over the years. As each country has an equal vote, Europe has a massively disproportionate number of sites compared to the rest of the world. Italy alone has more sites than the United States and Canada combined.

Applying for a site to get world heritage status can be very expensive. Xinning County in Hunan Province, China spent US$59m to get the Danxia Landform listed. Likewise, gaining world heritage status can be very lucrative. Places which are otherwise unknown can be put on the map and become a destination for tourists. One reason why Europe has so many world heritage sites is that it means more to Europeans, whereas most American probably have no idea as to its importance.

There are 10 criteria which world heritage sites must meet to be included on the list. They are:

Cultural criteria
(i) “represents a masterpiece of human creative genius”
(ii) “exhibits an important interchange of human values, over a span of time, or within a cultural area of the world, on developments in architecture or technology, monumental arts, town-planning, or landscape design”
(iii) “bears a unique or exceptional testimony to a cultural tradition or to a civilization which is living or which has disappeared”
(iv) “is an outstanding example of a type of building, architectural, or technological ensemble or landscape which illustrates a significant stage in human history”
(v) “is an outstanding example of a traditional human settlement, land-use, or sea-use which is representative of a culture, or human interaction with the environment especially when it has become vulnerable under the impact of irreversible change”
(vi) “is directly or tangibly associated with events or living traditions, with ideas, or with beliefs, with artistic and literary works of outstanding universal significance”

Natural criteria
(vii) “contains superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance”
(viii) “is an outstanding example representing major stages of Earth’s history, including the record of life, significant on-going geological processes in the development of landforms, or significant geomorphic or physiographic features”
(ix) “is an outstanding example representing significant on-going ecological and biological processes in the evolution and development of terrestrial, freshwater, coastal and marine ecosystems, and communities of plants and animals”
(x) “contains the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation”

No idea why this is a world heritage site
No idea why this is a world heritage site

The problem is these are all very subjective criteria and an argument could be made to include almost anything.

In the mental exercise I mentioned above, if you listed all the places in the world that you think are exceptional you might come up with several dozen or maybe even a few hundred. You probably won’t come up with over 900. Having taken care of the high profile sites like the Pyramids of Giza and the Great Wall of China early on, the sites which are now being added seem to be ever more marginal in importance. Some of the sites I’ve visited like The White City of Tel Aviv and the Holašovice Historical Village Reservation in the Czech Republic seem to have little or no value at a global level. This is a problem I fear will only get worse if they keep adding 20-30 sites each year.

World Heritage Site Trivia

Here are some fun facts about UNESCO World Heritage Sites:

  • The first world heritage site was the Galapagos Islands in Ecuador.
  • The country with the most sites is Italy with 47, which does not include sites in the Vatican or San Marino.
  • The largest site by area is the Phoenix Islands Protected Area in the nation of Kiribati in the Pacific Ocean. It has an area of 408,250 km2.
  • The smallest world heritage site is probably the Holy Trinity Column in Olomouc, Czech Republic. It is literally the size of a statue or fountain in a city square.
  • The southernmost site is Macquarie Island, Australia off the coast of Antarctica at 54°S.
  • The northernmost site is the Natural System of Wrangel Island Reserve, Russia at 77°N
  • The most sites any person claims to have visited (to the best of my knowledge) is 720 by Bill Altaffer.
  • This island of Surtsey in Iceland was created by volcanoes between 1963 and 1967. It was added as a world heritage site in 2008. It is of interest because no people are allowed on the island. Only 1 scientific team visits the island every 10 years to see how nature is establishing itself.

So Why Do I Do It?

The Grand Canyon would be on any list you make of the greatest places on Earth

The question still remains, “why do I go out of my way to visit world heritage sites?”

There are several reasons:

First, world heritage sites are the best the world has to offer. Yes, there are some stinkers in there, but more often than not I’ve been pleasantly surprised at a place that I otherwise knew nothing about and I would never have visited if it wasn’t on the list. If not for being listed I never would have visited the Temples of Horyu-ji, the Island of Rennell, Mulu National Park, L’Anse aux Meadows or Ceský Krumlov. As a rule of thumb, I can say that visiting a world heritage site will be worth the time and effort if you are in the area. It isn’t a guarantee but the odds are very good.

Second, it is more meaningful than just saying I visited a country. If someone says they’ve been to Egypt, what does that mean? Does it mean they visited the ancient Egyptian ruins? Does it mean they had a layover at the airport in Cairo? Does it mean they spent one night at a Hilton before leaving? It is a fundamentally different thing to say you’ve been to the pyramids than it is to say you’ve been to Egypt. It is more specific and it has more meaning. If you look the list of world heritage sites I’ve visited, you can have far greater understanding of where I’ve been and what I’ve done than looking at a list of political boundaries I’ve set foot in. You can see I only visited one site in Hungary, none in Slovakia and most of the sites in Australia and Japan.

Finally, having a list or some theme to your travels is fun. I don’t visit places just to check things off on a list. I’ve passed up many world heritage sites because they just didn’t seem worth the time and effort. I could probably have had 50-100 more sites under my belt if that was all I cared about. That being said, it is fun to have a list and it provides me an interesting hook to blog about and excuse to visit new places.


You don’t need to be a world heritage junkie like me, but you should take the time to see if there are any sites near locations you might be visiting. You might find some interesting places that otherwise might never have visited.

Humanity’s heritage is your heritage. Explore it.

  1. i appreciate your effort and admire your knowledge. UNESCO is suppose to preserve our common heritage, and it is should be unbiased.Now i understand the ‘price tag’ associated with them.some of the less fortunate nations in Africa and Asia who has very rich cultural heritage,who outdo Roman civilization by centuries is left to rot.
    If a nation is Rich and influence enough they can afford to preserve their values heritage.
    What have the world become,Money talks bull*** walks, will ultimately fail Human Race.

  2. Do you think as I do that the unique UK canal system should become a world heritage site. .

    • I don’t know much about it. I do know that the UK has a unique claim on many industrial sites which are important to the development of the industrial revolution.

  3. Hi Gary I am in the process of adding all the world’s UNESCO sites onto my experience listing site doolist.com and I wondered if anyone had visited them all. I typed it into Google and I found your site! What a great idea! I am very impressed with your story and think you’re inspirational…all the best on your travels! Dave

  4. I’m glad you posted this. I’ve been telling people “Oh, yeah it’s great. It’s a UNESCO world heritage site.” I never really knew what that was. Now I have a new list of stuff I need to check off.

  5. I’ve done most of the world heritage sites in Scotland and a few in England and Wales but it looks like I have a fair way to go until I reach your level.

  6. “Some of the sites I’ve visited like The White City of Tel Aviv and the Holašovice Historical Village Reservation in the Czech Republic seem to have little or no value at a global level.” – Gary, I think this comment shows you still don’t understand the inscription process completely. Tel Aviv was obviously inscribed under criterion 2 & 4 because it represents “an outstanding architectural ensemble of the Modern Movement in a new cultural context.” The wow factor is not a requirement for inscription. Outstanding universal value goes beyond aesthetics or beauty. Here’s a link to several hundred pages of documents you might want to read to understand how sites get inscribed and the elements that lead to successful nominations: Nominating properties to the UNESCO World Heritage List

    • P.S. The US doesn’t have that many sites because it boycotted UNESCO for 18 years. So no UNESCO sites inscribed during that time

      • I’m with Gary. My experience is more with Asia than Europe, the Middle East, Africa, etc. but the problem with programs like this is that they have to continue justifying their existence. The World Heritage Sites program wasn’t a bad idea and I think provides a good starting point when traveling. However, the sites that are truly part of the world’s heritage are usually pretty obvious and were added early on. To keep the program going, they have to keep adding sites, which means pulling in ever more marginal sites. As for the White City of Tel Aviv . . . I’m not sure if I visited it or not during my trip to Israel as an elementary school-aged person but it occurs to me that on some level you need a fair amount of time to elapse before rendering a judgment on what’s truly part of the world’s heritage. Somebody obviously thought the White City was but 100 years from now that may not be the case. Something like the Great Wall of China is pretty much set in stone at this point, no pun intended.

  7. 9 down….927 to go. Well maybe 800 and some if I skip the less exciting ones. Great post!

  8. Great info. I’ve been working my way through the US National Park system, and a lot of those are on the UNESCO list. It’s a little hard for me to believe Italy has more than the US, but it’s not a big deal. It’s funny that you mention that about the site in Iceland that no one visits- there are a few NP units here in the US that are also closed to the public. Expense is the reason I’m limiting my National Parks quest to the lower 48. I once figured it out and it would cost me the same amount to visit the 300+ in the lower 48 as it would to visit the 40 or so in Alaska, Hawaii and our overseas territories.

    • Visiting the National Parks in Hawaii isn’t actually that bad. I’ve been to all of them except for the former leper colony on Molokai.

      4 are on the Big Island, 1 is on Maui and 1 is on Oahu.

      The really difficult World Heritage Site in the US is Papah?naumoku?kea which consists of all the uninhabited islands in Hawaii west of Kauai. No one goes there and there are no regular trips there.

      I have told the tourism board in Hawaii to notify me if there are ever any diving or science expeditions that go there, but I’ve heard nothing so far.

  9. Gary, your coverage of the UNESCO World Heritage Sites has inspired me to add them to my bucket list. Yes, all of them. I’ve been to a few without knowing it, but now I want to visit even more! Keep up the great and inspiring work on your blog.

    • Keep in mind that visiting all of them is almost impossible and even if it were possible it would be amazingly expensive.

      2 places I’ve been trying to visit are Nahani National Park in the NWT of Canada and SGang Gwaay on Queen Charlotte Island in BC. Just getting there is a chore as you can only go at certain times and certain times of the year. You have to fly in and in the case of SGang Gwaay you have to take a several hour zodiac ride to get to the village.

      ..and that is only in Canada!

      Europe is the easiest place to visit large numbers of sites simply because they have the most and they are usually accessible by car or train.

      I’m planning to do a book when I get to 250.

      • You didn’t just say “impossible” did you?!?! ha! Yeah, I imagine some places can be very tricky to get to, but if I get a few hundred visited, I’ll be happy. And I’ll probably just keep visiting them until I can’t travel anymore. I’ll be looking forward to that book!

  10. Excellant article Gary… what a great explanation about what these sites are about!

    We even have a “UNESCO” category on our blog but never really got the significance till now so… thanks! :-)

    Again, great article!!

  11. I always go out of my way to visit world heritage sites as well- they are a great indicator of what to see, particularly if you don’t know a lot about a country.

    When I was in Laos earlier this year I went out to visit the Plain of Jars, an area that is lobbying for UNESCO status. They’ve been unable to obtain it so far b/c of all the unexploded ordinance lying around the sites. They are trying really hard to clean it up, as they know that if they achieve World Heritage Status (and in my view it’s certainly a worthy site) it will transform tourism in the area and bring in a lot more money. It was interesting to have a peek at the motivation and politics behind the sites.

  12. Thanks, Gary —

    I found this to be very enlightening and useful information for my own wandering and exploring. I had no idea there were that many sites and what the real significance and characteristics were.


  13. Thanks so much for posting that! Looking up the UNESCO sites was on my list of things to do – I was curious, but you answered all my questions! : )
