a mass of earth, usually formed with material excavated from the ditch, to protect the enclosed area from artillery fire and to elevate defenders to a commanding position overlooking the approaches to a fort.

a broad embankment of earth that supported the functioning elements of a permanent or semi-permanent fortification.  The parapet and banquette were built at the front of the rampart; ramps moved troops from the interior of the work onto the terreplein of the rampart.  In early forts, a rampart was often improvised by constructing double parallel revetments of logs and filling the intervening space with stones and hard-packed earth.  Ramparts typically were not a component of field fortifications but appeared occasionally in simpler form in some artillery works.  Sometimes called a bulwark.
