How Is This Roof Standing Without Any Support? 🤯

There's nothing holding up this roof. No pillars, no beams, [music] no hidden supports. So, why doesn't it collapse? At first glance, it looks like it's defying gravity, but the secret is an ancient building technique called the [music] Catalan vault. Used for hundreds of years in Mexico and other parts of the world, it's made by laying thin, lightweight bricks with a fast-setting mortar. Once the first [music] brick is in place, it helps support the next one. Brick by brick, a curved structure forms, and the entire [music] roof locks itself together. Unlike a flat roof, where the weight pushes straight down, this arch design spreads the load [music] outward toward the edges, making it incredibly strong without needing any support underneath.
