Within a campaign of underwater archaeological investigations in the shallows to the north-west of the island of Sant'Erasmo, in the northern lagoon of Venice, several sites have been identified that can be traced back to ancient embankment structures, in several cases to those known locally as ‘road-embankments’, lying under very thick layers of predominantly silty sediment. The attribution to this typology derives from merging the data collected in the two phases of the investigations: the large longitudinal development and more or less constant width of the findings detected with the hand-held metal probe and the nature of the same finds, consisting of wooden piles and accumulations of reused materials, basically bricks and amphorae, brought to light with the opening of small excavation tests. There is a constant divergence between the dating of the materials, all referable to the Roman period, and that of the wooden piles, which leads back to the late antique and early medieval periods. The evidence found contributes to defining the ancient lagoon landscape in an area close to the littoral zone.
Nell’ambito di una campagna di indagini archeologiche subacquee nei bassifondi a nordovest dell’isola di Sant’Erasmo, nella laguna nord di Venezia, sono stati identificati diversi siti riconducibili a strutture arginali antiche, in vari casi a quelle note localmente come ‘argini-strada’, giacenti sotto potenti strati di sedimento prevalentemente limoso. L’attribuzione a questa tipologia deriva dall’incrocio dei dati raccolti nelle due fasi delle indagini: il grande sviluppo longitudinale e la larghezza più o meno costante delle anomalie rilevate con la sonda metallica manuale e la natura delle stesse, costituita da pali lignei e accumuli di materiali di reimpiego, fondamentalmente laterizi e anfore, messi in luce con l’apertura di piccoli saggi di scavo. Si rileva una costante discrepanza tra la datazione dei materiali, tutti riferibili ad epoca romana, e quella dei pali lignei, che riconduce ad epoca tardo-antica ed altomedievale. Le evidenze riscontrate contribuiscono a definire il paesaggio lagunare antico, in una zona prossima al litorale.

Abstract
Within a campaign of underwater archaeological investigations in the shallows to the north-west of the island of Sant'Erasmo, in the northern lagoon of Venice, several sites have been identified that can be traced back to ancient embankment structures, in several cases to those known locally as ‘road-embankments’, lying under very thick layers of predominantly silty sediment. The attribution to this typology derives from merging the data collected in the two phases of the investigations: the large longitudinal development and more or less constant width of the findings detected with the hand-held metal probe and the nature of the same finds, consisting of wooden piles and accumulations of reused materials, basically bricks and amphorae, brought to light with the opening of small excavation tests. There is a constant divergence between the dating of the materials, all referable to the Roman period, and that of the wooden piles, which leads back to the late antique and early medieval periods. The evidence found contributes to defining the ancient lagoon landscape in an area close to the littoral zone.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
