RoeroWorld Heritage of Unesco

The ancient Roero’s area dates back to the Pliocenic period and his soil is mainly made of sand of marine origin mixed with clay and grey-blue marl.

This soil has been originated by an internal sea called Golfo Padano. Roero’s soil is the result of the sedimentation of mixed marine fossil debris and it is younger and less compact than Langa’s soil. We can enjoy the stratification of the soil in the gullies originated about 250.000 years ago when the river Tanaro deviated his course due to another river. The historians name this disruption “Cattura del Tanaro”. The result of the deviation of the river Tanaro is a deep erosion which gave birth to a real natural jewel which is named “Rocche”.

Roero is located on the left of the river Tanaro and his district is approximately 400 square km and contains 24 municipalities.

Dating 22nd June 2014 during the 38th Unesco meeting in Doha, Roero, together with Langhe and Monferrato, has been classified world heritage of Unesco.
