Batter
Batter
Is a term applied to walls built out of the upright, or gently sloping inwards: for example, the tower of Oxford Castle, and of St. Peter's Church (Oxford), of Isham Church (Northamptonshire), and some others, batter — that is, they are smaller at the top than at the bottom, the walls all inclining inwards. Wharf walls, and walls built to support embankments and fortifications, generally batter.
