The Menhirs at Clendy

45 menhirs are spread out in an oval array in the Neolithic site Clendy, on the shore of Lake Neuchâtel near Yverdon-les-Bains. Put up 6,000 years ago, they were re-erected in 1986.

Menhirs de Clendy, Yverdon-les-Bains

When the level of Upper Lake Neuchâtel decreased by 2.7 m after channeling the watercourses from the Jura (1869-1883), the menhirs appeared on the water surface in Clendy.

In 1896, engineer Charles de Sinner published a description of the site and affirmed that these blocks had been aligned by man. It was not until 1975 that his claim was confirmed by scientist and geologist Jacques-Henri Gabus.

These 45 erratic blocks - Alpine rocks swept along by the Rhône glacier – were cut into human shape. Some of them are 4.5 m high and weigh 5 tons. They are comparable to the carved statues of the Mediterranean Neolithic.

As the site was not covered with trees in those days, there was a view from east to west, from the rivers to the mountains, from the stars to the Moon.

After erosion caused by strong lake transgression, the menhirs started collapsing in 850 B.C. They were re-erected in 1986.

This unique site in Switzerland resembles the one in Carnac in France. Some claim that benign waves can be felt there.
