The village of Gravagna is divided into two hamlets, Gravagna San Rocco and Gravagna Montale, two distinct settlements that develop almost parallel in the northern part of the Civasola stream valley, along one of the most important and strategic natural routes for ascending from the Magra valley floor to the Roman pass of Sella del Valoria and subsequently to the Cisa Pass. This community has ancient origins and was densely populated until the early 1900s, when hundreds of residents from Gravagna left these villages in search of new fortunes and opportunities abroad, migrating to various European countries and the United States. The parish church of San Bartolomeo, located in Montale, is mentioned as early as the 11th century as a dependency of the Benedictine monastery of Montelungo, and it is likely one of the oldest in the entire valley, as evidenced by certain features of the masonry in the apse made with large sandstone and limestone blocks. In the hamlet of San Rocco, the current parish church was established in 1731 as a private chapel and was later transformed and expanded at the beginning of the last century, featuring a gabled façade characterised by a fine marble lunette.
