Moguntiacum — A settlement in Germania Cisrhenana also known as Mainz
The Roman stronghold or castrum Mogontiacum, the precursor to Mainz, was founded by the Roman general Drusus perhaps as early as 13/12 BC. As related by Suetonius the existence of Mogontiacum is well established by four years later (the account of the death and funeral of Nero Claudius Drusus), though several other theories suggest the site may have been established earlier.

he castrum was the base of Legio XIV Gemina and XVI Gallica (AD 9–43), XXII Primigenia, IV Macedonica (43–70), I Adiutrix (70–88), XXI Rapax (70–89), and XIV Gemina (70–92), among others. Mainz was also a base of a Roman river fleet, the Classis Germanica.

It served as a mint for the Romano-Gallic usupers.
