Pink Sandstone

Unlike pink granite (not to be confused!) which is made by the cooling magma, Erquy's pink sandstone is the result of the superimposition of layers of sand 470 million years ago. Its pink colouring is due to the presence of iron oxide, and its hardness, as a siliceous rock, make it a noble material, widely used in the early 20th century for building and paving streets. It gives the local buildings a special charm.
Pink sandstone is today being using by local craftsmen once more.

The Quarry lakes, known as the "Blue Lakes "

are the result of the quarrying of pink sandstone from the cliffs overlooking the harbour. Workmen dressed the stone on site and the paving stones were transported by wagon to the dock below. They were then loaded onto boats (like the Sainte Jeanne). Most were destined for the large Northern cities.

A festival of geology : le géofestival

An original invitation to discover Erquy, nicknamed "the pink sandstone Brittany", and its territory.

Some exhibitions, commented walks, fun itineraries and conferences about geology.
The first edition of the festival took place in Erquy in 2009.
