The Path of Ginocchielli di San Romualdo (St. Romualdo’s Knees) takes its name from the road traveled by the Saint to get to build the hermitage of Val di Castro.

Popular belief indicates that, in correspondence to a boulder, a miracle happened: it was here that the saint met the devil, who made the mules that transported the columns to the hermitage slip. The animals came out incredibly unscathed but left knee prints right on the boulder, where they are still visible.
