A given tile may have only 1 tile improvement; any attempt to build another one on the same tile will result in the previous tile improvement being replaced.
Note that most tile improvements only improve the tile yield, and thus have effect only if the relevant tile is being worked by a Citizen from a nearby city. Strategic resource improvements, however, also add the number of the relevant strategic resource to your total (regardless of the tile being worked, or not), while transportation improvements work at all times.
These improvements can be built anywhere there is suitable terrain.
|Tile imp||Tech required||Built on||Yield||Maint|
