What's the biggest Lego structure you've ever built? Chances are it's not nearly as big as this giant re-creation of the "2x4" brick that Lego unveiled Friday to celebrate the 60th anniversary of the iconic building blocks.
The monument weighs a super-hefty 1,200 pounds and stands 10 feet tall. It's made up of 133,000 individual bricks and took Lego's master builders more than 350 hours to construct. You can watch it come together in this time-lapse video from Lego.
The massive result will stand in New York City's Flatiron Plaza from Friday through 4 p.m. ET Sunday, the latter being the official anniversary date.
The "2x4" is not the very first brick that Lego made. The first ones were known as Automatic Binding Bricks when they launched in 1949. However, the two-studs-by-four-studs design debuted on Jan. 28, 1958, and hasn't changed significantly since.
