n Billund, everything is awesome. I was there back in June 2008 during an exclusive tour of the factory and it's a magical wonderland. I saw how bricks and minifigs are made. How they store themin a giant 65-foot-high Lego cathedral controlled by robots—which seems out of Willy Wonka. Then I visited their museum house—the original family home of the company founder—which has some of the best and most famous Lego sets in history on display.

But it was under that house where I found the Holy Grail of Nostalgia, a high security vault that contains every Lego set in history. This is the article I wrote about it back then. I realized it contains the reason why The Lego Movie hit me right in the feels.
