Kergadiou menhirs are a pair: the standing one (or should I say towering?) is 8.75ms tall and an utter beast! Some books say it's the second tallest menhir in Brittany.
Eighty metres away in the same field, its partially fallen twin is no less impressive. Lying like a beached whale at perhaps 25 degrees, like a giant sundial, it is an unbelievable 11ms long - 11ms! It is less of a menhir and more of a runway on an aircraft carrier. It simply invites you to run up its flat surface and stand on the summit from where there's a good 4m drop to the ground.
