After the destruction of "Vetera" a second camp was established at the Bislicher Insel, named "Castra Vetera II", which became the base camp of Legio VI Victrix. A nearby created settlement, which was inhabited by 10,000 to 15,000 former legionaries and others, was given the rights of a colonia in 110 AD by the Roman emperor Marcus Ulpius Traianus, who renamed the town "Colonia Ulpia Traiana". The colonia was a completely new town with a town wall and other buildings like an amphitheater. For this town the old settlement was completely destroyed. The colonia became the second most important commercial post in the province of Germania Inferior, surpassed only by "Colonia Agrippinensis" (today's Cologne). In 122, "Vetera II" became the camp of Legio XXX Ulpia Victrix, replacing VI Victrix which had moved to Britannia.
