Inns and Cathedrals, originally published as the Expansion, is the first expansion to the board game Carcassonne. It was first published as 2002, and contains a number of new tiles and one new figure.
It contains eight grey normal followers, allowing a sixth player to join the game. It also contains a Big Follower for each player which can be played as a normal followers but counts as two followers for the purpose of establishing which player gets points from a feature. It contains a number of new tiles, including two city tiles with a Cathedral, which causes the city to score three points per tile and pennant when the city is completed, or no points if it is incomplete at the end of the game. The expansion contains six tiles with an Inn on the Lake next to a road, this causes the road to be worth double points when completed, or no points at the end of the game.
