The stream Turrite Cava is spanned by several medieval bridges. One of those is part of a paper mill and is situated in the district "I Molini". It is a sandstone footbridge consisting of a single round arch. Together with the bridge, the remains of the decaying water-mills giving the name to the area are also open to visitors. The bridge was built by local masons in the 14th century.
