Don't forget the suffix -am also means "towards this City/place. It could be "to Cola" or "to Col" or "to a collar (in the geographical sense)". There are a lot of mountains in France that have the word Col in their name.

You are correct, the accusative case can mean "to a place", like "Romam", "to Rome", but I don't think this is the case here.
