Nearby Loppia, in the district of Barga, the stream Loppora is crossed by a noteworthy footbridge with a hump-backed and slightly asymmetrical structure. The highest point of the road running along the bridge is not placed in its centre, and the ascent and descent are not the same length. The peculiar bridge outline, whose asymmetry is similar to the impressive one of the Devil's Bridge in Borgo a Mozzano, is due to the fact that the two stream banks are not levelled, and that the bridge follows the line of the road it was conceived for: the old road from Loppia to Filecchio. Supported by a round-headed arch, the sandstone bridge was built in the 14th century by local masons and underwent reconstruction in the 18th century. This is proved by the research study of Antonio Nardini of the section of Barga of the Istituto Storico Lucchese.
