Clastidium

Clastidium is a Ligurian city of the tribe Marici that controls a major route across the Po river to Ticinum. It would gain its largest claim to fame in 222 BCE as the site where Roman general Marius Claudius Marcellus would slay the Insubrian king Virdumarus in hand-to-hand combat, making him one of only three Romans to ever earn the prestigious honour of the spoila opima.
