Cities

A meeple in a city is a knight. A city is complete when it's fully enclosed by walls with no gaps inside. It then scores 2 points per tile plus 2 per coat of arms, and its meeples return. An unfinished city at game end scores only 1 point per tile and 1 per coat of arms.

With Inns & Cathedrals: A completed city with a cathedral scores 3 points per tile and per coat of arms — but nothing if it's unfinished at game end.

With Traders & Builders: Completing a city with goods symbols gives trade goods to whoever placed the completing tile.
