Why Are Some Window Bars Curved at the Bottom?

If you’ve ever walked past an older building and noticed window bars that bulge outward or curve at the bottom, you’re not alone. At first glance, they might look decorative or even oddly designed—but those curves serve a practical purpose rooted in history, safety, and everyday life.
