[1] These avenues are composed of basalt stones which are placed at an angle, and menhirs are arranged in three rows in each.

It has been attributed in recent years to anti tank defences constructed in the Second World War, but recent research favours an interpretation that the site, if not its arrangement, dates to the neolithic or bronze age and perhaps shares a context with the Carnac stones of France.

The rows of stele begin at a rocky outcrop and follow the valley topography for 500 metres.

[4] The arrangement of the stone rows were integrated into a modern anti tank military barrier.

As there is no firm dating, it is unknown to what extent and in what form the avenues predate this modern use.
