Forteresse de Polignac – Volcanisme

Polignac volcanoes at liberty About 3 million years ago, when Auvergne mastodons roamed the region, a volcano erupted. The lava solidified when it made contact with the water, giving rise to the rock that was used as a pedestal for the fortress.

Description

The Polignac site is located in the volcanic basin of Le Puy-en-Velay, extending from Chaspinhac in the east to Devès in the west.
The volcano emerged from under a vast lake that covered the area several million years ago. It is an example of a submarine volcano, like the Corneille rock and the Aiguilhe rock.
As part of the "Volcanoes at liberty" programme, the base of the fortress is a great place for visitors to observe the volcanic landscape and the types of rocks all around, and to take a quiz.
A fun way to explore the natural heritage and the volcanic landscape (paid admission to the fortress)
