These days in the Netherlands we have a law that demands of that all big projects which affect the countryside, has to create a space in time for archeologists to inspect the site in question before the construction commences. In this case extensive railroad works gave archeologists a chance to start digging again. On this day a piece of Roman road was shown for the public.
Nearby (almost literally a stones thrown away) is/was the Roman castellum of Fectio. A long time important support point including a harbour. Fectio was built A.D. 4 - 5 during Tiberius' campaigns. At that time the Romans still tried to make the Elbe their definitive border.
