BackArrowGreen.png Back to List of improvements in Civ5

In Civilization V and its expansions, a unique improvement (UI) is a special tile improvement that can be built by only one of the civilizations in the game. Unlike unique buildings and unique units, a unique improvement never replaces a standard improvement, and civilizations that don't have one will have a unique building or a second unique unit instead. Additionally, any civilization that works a unique improvement's tile can benefit from its effects.
