It’s a bird, it’s a plane, it’s….a lego tower? The world’s largest lego tower was built in Seoul, Korea at a height of 31.9 meters, that’s approximately 105 feet. If you didn’t know already (we sure didn’t), France held the record for one at a height of 31.6 meters.

Bored with the typical 1-footer tower and wondering how to create your own lego empire? All you need is 4,000 children, five days, and 50,000 bricks.
