When I was a kid I loved to build towers from Lego, making them as tall as my little arms would allow. But my towers had nothing on this monolith in Brazil.

Impressively it was a group of around a thousand local children that made this mammoth Lego structure. They needed a little mechanical help to get the blocks to the tippy top of the tower, but they assembled every toy brick themselves.

The building measures more than 102 feet, and took around 500, 000 blocks to complete. That’s a lot of sets of Lego! But it seems to have been worth the effort, as the Brazilian kids snatched the world record from Chile for their efforts.
