A building can be razed for half its cost back; the plot is freed.
1Tap a standing building on the island: its card opens with «Raze» at the bottom.
2The game asks once more. Half of every standing level comes back: silver to the treasury, goods to the yard. Work in progress is refunded in full.
3You cannot raze what others stand on («something rests on it») — nor the Town Hall or the Grail. A razed dwelling loses its waiting men, and its tier is no longer hired.
