The “Impianto Idrovoro del Torrione” (pumping station) was created between 1920 and 1923. Through a system composed of three pumps, it was possible to drain the excess water in the Crostolo stream. In the site known as “Torrione” - halfway between Gualtieri and Santa Vittoria - you may still find many artifacts, dating back from the 16th century to the present day. From the banks of the Crostolo it is possible to enjoy a suggestive view of the complex water system of the lowlands.
