Opened in 1922 and currently able to handle more 100,000 fans, Ohio Stadium in Columbus, Ohio, is a sight to behold. It's almost as amazing as the Lego replica sitting in Paul Janssen's basement.

The 42-year-old Ohio State University professor tells NPR's Robert Siegel on All Things Considered what it was like to build the horseshoe-shaped stadium out of 1 million Lego pieces. Built at a scale of 1:120, it took years of planning, collecting pieces and building to complete the project.

The mini-stadium can seat only 6,000 Lego people — that's thanks to issues of scale, not Janssen's work.

You can see the results for yourself in the photos below, and in a full photo gallery over at The Columbus Dispatch.
