The double arch stone bridge was built in the 17th century, and is one of the most distinctive sights in the village. The economy in the valley consisted mainly of farming and grazing. There was added income, from emigrants who went to Italy, especially Palermo. In 1873, they began to systematically produce granite from quarries in Lavertezzo. In the last decades of the 20th century Riazzino developed into a shopping and recreation center. By 2000, the agricultural sector still provided a good one-tenth of the jobs in Lavertezzo.
