The two dugout canoes displayed at the museum were found in 1940 during the excavations of an artificial canal in Valle Isola, in the drainaged area of Comacchio Northern valleys, Ferrara province (location Casone Gaiano). Starting from the discovery until 1948, when the canoes were recovered and brought to the National Archeological Museum of Ferrara, several events happened in the area: a change of the environmental conditions, damaged caused from people looking for timber, further findings and buried once
again. Among those ones, there are two trial excavations worth to mention conducted by the archaeologist Fernanado Malavolti with the aim to check the stratigraphy and layers of the soil. It certainly did not help the preservation of the area. No materials were found except for a fragment of a late roman time amphora, recovered from the layer of shells in the bottom of the ancient valley, which has allowed us to hypothesize the dating of the finds to III-IV century AD.
