When a city is destroyed, there will be ruins on the tile formerly occupied by the city. I could remove the ruins by pillaging it, but will there be any material impact on the game if I choose not to remove the ruins? What exactly is the use of ruins?

1 Answer

In all built-in rulesets that have ruins, ruins have no effect on gameplay.

Ruins mark the former site of a city that was destroyed or abandoned. They have no effect on gameplay.
