Carrowmore is the largest cemetery of megalithic tombs in Ireland. The tombs are spread out over 3.8 sq km (1.5sq mi) in the shadow of the Knocknarea to the east, over a number of fields and townlands, most of them situated near the road. Carrowmore's placement on a low-lying gravel ridge contrasts to the hilltop situation of other cemeteries; each mounment stands on its own little eminence.
Nearly 100 ancient monuments were originally present on this extensive site. Academic vandalism in Victorian times and modern gravel quarrying have left only about 65 sites, but the atmosphere of the area remains quite extraordinary. The majority of tombs are a mixture of small passage-tombs and dolmens, usually surrounded by a stone kerb and constructed with the large rounded granite boulders of the area. On this site there are several examples of what appear to be stone circles but which are, in fact, the kerbing stones of cairns which have disappeared. Some, however, are considered transitional forms between the heavy kerbs of cairns and the true free-standing stone circles.
