It could still be treated as one, nonetheless. Most people playing this wouldn't know what 'Carcere' even means so they would just assume that it should be a proper noun, and since the game delineates it as a specified location, it arguably should be treated as one.

I'd even go so far as to call this a 'localization failure', given how rarely do we see the root word for 'incarcerated'. The Japanese text probably just called it a 'jail' or 'prison', so it would have been better to just stick with the translated script content and not try to fluff it up with garbage.
