The small town of Bistrigna, formerly part of the Monfalconese Desena (i.e. the set of rural villages adjacent to the walled city), is on the edge of the coastal marshes that have now been reclaimed. In the centre, the small church of San Valentino, which was almost totally destroyed during the First World War and rebuilt after the war, preserves an altarpiece in galvanised sheet metal, made by Clemente Delneri in 1914 and depicting St. Valentine, on which you can still see the signs of war. In this village there was a historic mill, whose presence is documented as early as 1588 and which was active until the mid-eighteenth century. The canal that fed it disappeared after the reclamation works. The locality has several springs: once this water was used in the rice fields that were located between Bistrigna and the coast and the mill that served it remained active until the beginning of the twentieth century.
