There is a series of fab articles by Paolo Rumiz on La Repubblica these days titled “Appennino, il cuore segreto”: he’s travelling along the Apennines with a Topolino (a great tiny old car) and he spent a couple of days nearby.
There’s the links to the two articles regarding northern Le Marche (for those of you who can read Italian!) Nella Gola del gigante from Pennabilli to Fonte Avellana Monastery and Il suono del silenzio from Fonte Avellana down to Fabriano
For you to have an idea of the beauty of the places he’s visiting, here’s a photo of the Scriptorium of the Fonte Avellana Monastery.
