Carcassonne: German Cathedrals

From BoardGameGeek:

Carcassonne: Cathedrals in Germany is a mini-expansion of six tiles for Carcassonne with each tile featuring a well-known cathedral from Germany. If a meeple is placed as a thief on a road connected to a cathedral, then the thief earns double points for each road segment rather than for each tile. Alternatively, a meeple can be placed on the cathedral itself as a bishop, and if all of the roads connected to the cathedral have been finished before the end of the game, the bishop scores the player 1 point per road segment. This expansion was first available during the Easter season (through April 3, 2016), from the Publisher's online store, then again in October 2016. Part of the Carcassonne series.
