Carcassonne: Abbey & Mayor

Instead of drawing and placing a Land tile, you may place your Abbey tile; it may only be placed in an empty space surrounded on its four orthogonally adjacent sides (i.e., to fill a 1-tile hole), and you may not place it if no such hole exists (page 2).

Yes — you may place a meeple as a monk on the Abbey; the Abbey behaves like a monastery, completes the sides of adjacent tiles, and is scored identically to a monastery (score any features completed by its placement) (page 2).

A mayor's strength equals the number of coats of arms (shields) in the city it occupies (normal meeple=1, large meeple=2); when scoring a completed city each player's total strength is added and the highest-strength player(s) score the points (ties all score full); a mayor in a city with no coats of arms has 0 strength (page 3).

You may place a barn on the junction where four tiles meet only if the corner of each of those four tiles depicts field (i.e., a pure 4‑tile field junction); you may place a barn on a field already occupied by farmers but not on a field already occupied by another barn, and a placed barn remains in play until the game end (pages 3–4).

If you place a barn into a field with farmers that field is scored immediately as at game end (the player with most farmers scores 3 points per completed city) and those farmers are returned; if a tile connects a farmer-occupied field to a barn-occupied field that connected field is scored that turn for 1 point per completed city and farmers are returned; at game end each barn scores 4 points per completed city in its field (pages 4–5).

A wagon may not be placed in a field but may be placed on roads, cities, monasteries/abbeys like a normal meeple; when its feature is scored it scores like a normal meeple and then you may either return the wagon to your supply or move it to a directly adjacent unoccupied, incomplete feature (same tile or orthogonally/diagonally adjacent); if no such move exists the wagon must be returned (page 5).
