\Nu*ra"ghe\, n.; It. pl. {-ghi}. Also Nuragh \Nu"ragh\,
etc.[It. dial. (Sardinia) nuraghe).]
One of the prehistoric towerlike structures found in
Sardinia.
      The so-called nuraghi, conical monuments with truncated
      summits, 30-60 ft. in height, 35-100 ft. in diameter at
      the base, constructed sometimes of hewn, and sometimes
      of unhewn blocks of stone without mortar. They are
      situated either on isolated eminences or on the slopes
      of the mountains, seldom on the plains, and usually
      occur in groups. They generally contain two (in some
      rare instances three) conically vaulted chambers, one
      above the other, and a spiral staircase constructed in
      the thick walls ascends to the upper stories.
