They range from rude menhirs a few feet high to elaborately sculptured monoliths of too ft.
And yet in the European Stone age which followed, the age in which the great menhirs and cromlechs were erected, in which the domestication of animals began and the first corn was sown, we find in the strata no image of man or beast, big or little.
The most remarkable consist of long avenues of menhirs or standing stones; but there is also a profusion of other erections, such as dolmens and barrows, throughout the whole district.
About half a mile to the north-west of the village is the Menec system, which consists of eleven lines, numbers 874 menhirs, and extends a distance of 3376 ft.
These three systems seem once to have formed a continuous series; the menhirs, many of which have been broken up for road-mending and other purposes, have diminished in number by some thousands in modern times.
