An article about the pros and cons of establishing a site as a World Heritage Site. It is specific to three sites recently nominated in Saudi Arabia, but puts them into the context of more general issues: "Automobile traffic is becoming a major threat to many other World Heritage sites. The road close to Stonehenge in the United Kingdom has threatened the integrity of the site. The proposal to build a highway close to the site of the Great Pyramids in Egypt from Giza to Dahshur was stopped by the Egyptian authorities at the request of UNESCO. The World Heritage Convention, referring to the List of World Heritage in Danger, mentions the serious threat of rapid urban or tourist development projects."
