[00:00:00]Check this out. There are no pillars or supports [music] under the ceiling, yet it doesn't collapse. It looks like these builders are defying gravity, but this is an ancient technique [music] called a Catalan vault. They use super light, thin bricks, and a special fast-drying mortar. The moment the first brick sticks, it supports the next one. Piece by piece, they lay them in a curved pattern until the entire ceiling locks itself into place. [music] On a flat ceiling, weight pushes straight down, but this arch design forces all that weight outward to the [music] sides. The most mind-blowing part, no machinery.

[00:00:28]This is 100% done by hand. One tiny slip and the whole thing could come crashing down.
