The third group of standing stones in Carnac is found further to the east. It is the smallest but probably the best preserved of the groups. Several features make it unique: it is clearly oriented from east to west (and not south-west to north-east); the layout is exceptionally compact (only 350m in length with 13 lines initially spread over a width of 140m); at least one section of lines (the southernmost lines) is clearly arranged in a fan-shaped pattern open to the west towards the enclosure; the northern lines are sub-parallel, their length decreasing as they approach the periphery, creating a fan shape impression similar to that visible to the south; in the centre, two of the longest lines seem to form a "main avenue" leading in the direction of the north-western corner of the enclosure; the enclosure is almost square (80x90m), its 39 remaining stones neatly marking three sides of the square (the fourth side, to the north, has completely disappeared).
