Francs rhénans
Colonia was pillaged several times by the Franks in the 4th century. Two lavish burial sites located near the Cathedral date from this period. In 355 AD the Alemanni tribes besieged the town for 10 months, finally taking and plundering it. At the time, the garrison of Colonia Agrippina was under the generalship of Marcus Vitellus. The Romans re-occupied the city several months afterwards by Julian. The city finally fell to the Ripuarian Franks in 462 AD.
