Rarely does an architectural feature associated with one building type suddenly find itself used across the board. Battlements are a case in point - originally practical in application they lost their original function and became adopted as a decorative feature. Over a thousand years their use jumped from castles to churches and thence to public buildings of all sorts. They have been used for prestige, to create a sense of history, to define a building type. This lecture looks at their application in many different buildings and shows how each period of history - including the present - has reinvented the battlement to make a statement.
