Celtic Trail

36 km - 1.700 m D+

Following the footsteps of Etruscans and Celts in the Idice Valley

The Consul Caio Flaminio built the ancient Roman road Flaminia Militare in 187 BC to join Bologna to Arezzo.


But before then?


The Monte Bibele area represents the most important Italian archaeological complex, and one of the most important in Europe, as far as the Celtic civilization is concerned.

The Archaeological Museum of Monterenzio reconstructs the history of the presence of man in the Bolognese Apennines, especially in the Idice and Zena valleys, from the earliest evidence of the stone age to the Roman age.


We will walk these territories, from Monte Bibele to Monterenzio, immersed in Nature and History.


The competition will take place within the Celtic Culture Festival

"I Fuochi di Tranis".

History  Read more

The Monte Bibele massif, located between the two valleys of the Idice and the Zena, has been the subject, since 1973, of archaeological research that has revealed an Etruscan-Celtic settlement composed of a built-up area, a burial ground and two places of worship.


It was a community of Etruscans who, around 400 BC, tired of living in insecurity, danger and looting due to Celtic raids on the plains, moved to this mountain to build a new village.


Despite the inaccessible nature of the site, the village of Monte Bibele was conquered by the Romans and destroyed by a relentless fire between 200 and 187 BC.
