A watchtower, roadside inn or temple can become a focal point of a battle. Buildings offer substantial protection to those inside, and are a good vantage point for troops with bows, handguns and other ranged weapons. Warriors firmly ensconced in a building can only be driven out by a determined assault.

Players should identify at the start of the game all pieces of terrain for which they are going to make use of the buildings rules given here. This is important, as during the game these rules may give a clear advantage to some infantry units. Players may agree to treat some buildings as impassable (very small ones, or those with a strange shape, for example...) and use these rules for other, more normal, ones.
