You’ve seen them.
On brownstones in Brooklyn.
Victorian homes in San Francisco.
Colonial buildings in the Caribbean.
Window bars that curve outward at the bottom, like a gentle belly or a soft wave—almost as if they’re bowing to the street below.
At first glance, you might think:
“That’s just for looks.”
But here’s the truth:
👉 That curve—called a "potbelly"—isn’t decorative.
It’s brilliantly functional.
And once you know what it does, you’ll never look at window bars the same way again.
Let’s uncover the surprisingly smart reasons behind this classic design—where beauty meets physics, safety, and everyday life. ✨💛
