Gorge of Sant Miquel del Fai Nature · Bigues i Riells del Fai, Vallès Oriental, Barcelona Image of Bigues i Riells del Fai, not of the place itself. The Sant Miquel del Fai gorge opens beneath the Bertí crags, at the head of the Tenes valley (Bigues i Riells del Fai, Vallès Oriental). The Rossinyol stream forms a small pool beside the priory and then plunges into a waterfall; below it lie the Coves de Sant Miquel, a large cave hollowed out by the water over the centuries. The sanctuary, founded around 1006 by Gombau de Besora following a donation made in 997, housed Benedictine monks until the 16th century; the current building dates from the 15th century, though it retains a Romanesque church carved entirely out of the rock, unique in Catalonia.
