Sant Miquel del Fai Monument · Bigues i Riells del Fai, Vallès Oriental, Barcelona The sanctuary of Sant Miquel del Fai stands on a cliff at the head of the Sant Miquel valley, in the area of the Cingles de Bertí, in the municipality of Bigues i Riells del Fai (Vallès Oriental). The priory was founded by Gombau de Besora, lord of the castle of Montbui, after receiving the donation of the alou of Fai in the year 997, around the cave where Saint Michael the Archangel was venerated; in 1042 it became linked to the monastery of Sant Víctor de Marseille. The present building, a fine example of Catalan Gothic, was erected in the 15th century over the earlier church. Below the monastery, the Rossinyol stream forms a waterfall and, a little further on, the larger Rossinyol waterfall, at the foot of which open the caves of Sant Miquel, a hollow carved out by water. The complex reopened to the public in 2023. Photo: Elmoianes (CC BY-SA 3.0) What to see and do in Bigues i Riells del Fai
