The Menec "group of standing stones" is the westernmost of the largest Carnac megalithic monuments. According to latest counts, it consists of 1,050 menhirs. It stretches over 950m in length, lying south-west to north-east.
The monument starts in the south-west with an oval enclosure (70 x 90m). Some of its 71 remaining blocks can be found between the buildings of the village of Le Menec. The village was probably built during the Middle Ages, the megalithic monument having been used as a line of defense.
