This prison cell had already collapsed and been abandoned.
But apart from the rust and corrosion on the broken cross-sections of the smashed bars, there was no such sign anywhere else.
An abandoned place obviously would not have anyone specially come to maintain it.
Which meant those coatings were still working even now.
