NICE BUT NOT MUCH TO IT
You can visit this ruin from two streets, though those two streets aren't at all interconnected (you have to walk around).
You can see it from the street level, but you can't walk around the ruins yourself.
It's an interesting piece of Roman history, but you won't be here any more than 5 minutes, as there's not much more to see other than what you see in the pictures.
