- "The remains of some mighty fabric, hurled into desolation by a tremendous earthquake, or some other equally terrible convulsion of nature."
- –Philip Dixon Hardy
The Giant's Causeway is a 2-tile impassable Natural Wonder available in Civilization VI with the Vikings Scenario Pack. The Giant's Causeway occupies one Coast tile and one land tile (either a Grassland or Plains). Each wonder tile provides +2 Appeal to adjacent tiles.
Whenever a land combat unit moves adjacent to the Giant's Causeway, it receives a one-time "Spear of Fionn" bonus, permanently increasing the Combat Strength of the unit by +5. This bonus is reset if the unit is upgraded.
While the causeway is impassable, it is not a mountain, and ranged units can shoot over it.
Clusters of geometric columns known as the Giant's Causeway can be found along the coast of Northern Ireland. The columns vary in height, like a pipe organ that got away from itself. The columns closest to the coast disappear into the North Channel, while others jut out of the ground like basalt palisade walls. Legends claim the causeway was built by Irish giant Finn MacCool, who had been challenged to a fight by Scottish giant Benandonner. (Geologists disagree, connecting the pillar formation to volcanic activity 50 million years ago.)
- The Giant's Causeway is the only natural wonder in Civilization VI that must occupy two types of terrain.
- Along with Eyjafjallajökull and Lysefjord, the Giant's Causeway was the first natural wonder to be added to Civilization VI in an expansion.
