We're no strangers to oddball architecture -- we see the weirdest buildings all the time. But we haven't seen anything quite like this: a pavilion made of 45,000 recycled milk cartons. Be still our hearts: It's environmentally friendly, too!
The Tetrabrik Pavilion in Grenada, Spain, was the brainchild of architecture firms CUAC Arquitectura and Sugarplatform. As our friends at Curbed noted, the pavilion snagged a spot in the Guinness Book of World Records for the largest structure made of recycled materials. (It was 100 feet long by 50 feet wide.)
The firms gathered discarded milk cartons from 100 colleges to make their masterpiece. The structure was built in 2011 as a way to create awareness around World Recycling Day. Eventually, the whole project was shipped off to a recycling plant. But, hey, it's legacy clearly lives on. Click through the gallery below to see the dynamic Tetrabrik Pavilion.
