These are the bronze doors from the Castello Nuovo in Naples. Apparently someone wanted in and fired an iron cannon ball at them and the cannon ball got stuck in the doors. I’m not sure if that means it was a lousy cannon ball or a strong door. Either way, there it is. I’m not sure who fired it, but Napoleon comes to mind as a possible culprit. I’ll have to do some research on that. If anyone knows, tell me. The doors themselves are covered in wonderful reliefs produced during Alfonso I’s reign as king of the two Sicilies. They show his military campaigns juxtaposed with scenes from the Trojan War. Alfonso wasn’t shy about self-aggrandizement.
