Ubsunur Hollow is a four-tile passable Natural Wonder in Civilization VI: Rise and Fall. Ubsunur Hollow appears as a Marsh on Tundra tiles. Each Wonder tile provides 2 Faith Faith, 1 Food Food, and 1 Production Production. Ubsunur Hollow increases the Appeal of adjacent tiles by +2.

Like normal Marsh tiles, Ubsunur Hollow tiles have a Movement Movement cost of 2, and reduce the Strength Combat Strength of defending units by -2.

Discovering Ubsunur Hollow grants +1 Era Score, or +3 Score if the player is the first to do so.


Each Ubsunur Hollow tile has a yield of 2 Faith Faith, 1 Food Food, and 1 Production Production. Since Faith Faith is often hard to generate early in the game, incorporating the natural wonder tiles can provide a vital head start in founding a Pantheon before any other player. Ubsunur Hollow also helps in making a tundra start less taxing for the Russians, Canadians, and anyone else who happens to spawn there. In time and with some planning, it can also make for an easy National Park or two.

Unfortunately, as with all natural wonders, the Ubsunur Hollow tiles cannot be developed or improved. Because of this, natural wonders may be more of a hindrance than an asset later in the game - a natural wonder in the heart of a city can spoil adjacency bonuses for Farms and District Districts. In general, passable wonder tiles are significantly better than an unimproved tile of any kind, though they are often less productive than an ordinary tile with a tile improvement or district.

If you have control of this Natural Wonder, consider pursuing Charles Darwin in order to receive his maximum reward of 2000 Science Science.

Civilopedia entry[]

The land of Ubsunur Hollow (or “Uvs Nuur Basin”) is a pocket in time. Few signs of human life mark this Eastern Siberian region, but for the barrows dug for the ancient dead, massive stones erected as ceremonial monuments, and the haunting sounds of Tuvan throat singing.

The basin, just smaller than Puerto Rico, spans multiple biomes. All manner of unique species find a home in the Hollow’s deserts, marshes, tundra, and saltwater lakes. One such animal is the endangered snow leopard, once hunted to near-extinction. Now that the area is a protected reserve, the leopards can repopulate without fear of natural predators (beyond the occasional farmer concerned about their livestock).


  • Ubsunur Hollow is the second-largest real-life natural wonder to appear in Civilization VI by area. It covers roughly 70,000 square kilometres (~27,000 square miles), second only to the Great Barrier Reef's total area of 344,400 square kilometres (133,000 square miles). Bizarrely, Ubsunur covers four tiles, while the reef only covers two.
