The Collaborative International Dictionary of English v.0.48:

Rampart \Ram"part\ (r[a^]m"p[aum]rt), n. [F. rempart, OF.
   rempar, fr. remparer to fortify, se remparer to fence or
   intrench one's self; pref. re- re- + pref. en- (L. in) +
   parer to defend, parry, prepare, L. parare to prepare. See
   Pare.]
   [1913 Webster]
   1. That which fortifies and defends from assault; that which
      secures safety; a defense or bulwark.
      [1913 Webster]

   2. (Fort.) A broad embankment of earth round a place, upon
      which the parapet is raised. It forms the substratum of
      every permanent fortification. --Mahan.
      [1913 Webster]

   Syn: Bulwark; fence; security; guard.

   Usage: Rampart, Bulwark. These words were formerly
          interchanged; but in modern usage a distinction has
          sprung up between them. The rampart of a fortified
          place is the enceinte or entire main embankment or
          wall which surrounds it. The term bulwark is now
          applied to peculiarly strong outworks which project
          for the defense of the rampart, or main work. A single
          bastion is a bulwark. In using these words
          figuratively, rampart is properly applied to that
          which protects by walling out; bulwark to that which
          stands in the forefront of danger, to meet and repel
          it. Hence, we speak of a distinguished individual as
          the bulwark, not the rampart, of the state. This
          distinction, however, is often disregarded.
          [1913 Webster]
