Why Is St. Florian's Gate Still Standing in Kraków?

Kraków was once wrapped in thick medieval walls - towers, moats, multiple gates. Almost all of it was demolished two centuries ago. One gate survived. And the reason it's still standing is, honestly, the strangest argument in the city's history - something you'd never guess looking at it. Next time you're in the Old Town, walk through it and you'll never see it the same way again.
