Isn't that where the romans killed eachother?

Didn't they do that all the time LOL!
If you're thinking of the Rubicon that is further south and flows into the Adriatic
Torino itself was a large Roman town as are many Italian towns!!
Many towns including mine have kept the original Roman street plan superimposed with medieval structures.
My town is unusual in that the Decumanus Maximus is not north south orientated, due to the town being built on an escarpment at the confluence of 2 rivers.
PS Name 3 Italian cities which have kept their original Roman name!!
