Treva
Treva is the historical name of a settlement during the short-lived creation of the Roman province of Germania, at the site of the modern city of Hamburg in Germany.
History
The Romans reached the Elbe river under Augustus and conquered all the German territories west of this river.Some evidence indicates that they built a "marching camp" in a small island in the estuary of the river Elbe, in a place where their ships could arrive when sailing from Flevum - a Roman port near the Rhine river.
This place was called "Treva" and later probably had a small vicus populated by local Germans with some Roman merchants. The origin of the name is similar to the Latin name of Trier: tre from Latin "trans" and va from Germanic "var".
Indeed Lucius Domitius Ahenobarbus commanded the Roman army to the area of Treva and crossed the Elbe around 4 BC, during which he set up an altar to Augustus. His campaign followed the one with the creation by Drusus of small fortifications along the rivers Weser and Elbe, done some years before.
So, after Drusus, Ahenobarbus penetrated further into the country than any of his predecessors had done.
Furthermore, the future emperor Tiberius campaigned extensively while in Germany, even conducting some amphibious operations along the Elbe River in 5 AD and certainly landing also in the surroundings of Treva.
We have the description of these landings from one of his officers, named Velleius Paterculus, but it is not precise.
Later, Germanicus in 15 AD reached Treva and again crossed the Elbe river in his military campaign, before the final withdrawal of the Romans west of the Rhine river.
Claudius Ptolemy reported the first name for the vicinity as Treva. He also indicated that Treva was at the intersection of ancient commercial routes that have been used, among other things, for transporting the then very valuable amber.
The actual name Hamburg comes from the first permanent building on the site, a castle which the Emperor Charlemagne ordered constructed in 808 AD. It rose on rocky terrain in a marsh between the River Alster and the River Elbe as a defence against Slavic incursion, and acquired the name Hammaburg. Nothing remained of the castle, St. Mary cathedral was built on this site, demolished in 1807.
Recent archaeological discoveries in the center of Hamburg have proved the existence of a trade settlement during Roman times. Furthermore, some gold Roman coins have been discovered in Lokstedt.
