From iron works in Burkina Faso that date back nearly three millenniums, to the fortified and planned city of Jaipur in India, to the Guggenheim Museum in Manhattan, Unesco has added a broad array of cultural and natural marvels to its World Heritage List.

To be included on the list, a site must meet at least one of 10 criteria, like being a landmark of human history or culture, an ecological wonder, or “a masterpiece of human creative genius.” Unesco’s World Heritage Committee considered 35 nominations this year and accepted 29 from around the world, some of them composed of multiple sites, covering the full range of categories.

That is “a relatively high but not unusual number,” said Mechtild Rössler, the director of the organization’s World Heritage Center in Paris.
