Batter in construction is a receding slope of a
wall, structure, or earthwork. A wall sloping in the opposite direction is said to
overhang. The term is used with buildings and non-building structures to identify when a wall is intentionally built with an inward slope. A
battered corner is an architectural feature using batters. A batter is sometimes used in
foundations,
retaining walls,
dry stone walls,
dams,
lighthouses, and
fortifications.
