Improvement

The various Improvement in Civilization VI.

Improvements are built by particular units on almost any tile within your cities that is not occupied by a city center, district, mountain, natural wonder, or world wonder. The type of improvement that can be built on a tile is determined by the qualities of the tile including the terrain and resources.
