You've probably seen plenty of impressive Lego projects surface over the years, but we're really blown away by this massive, intricate recreation of Harry Potter's Hogwarts School of Witchcraft and Wizardry. As reported by The Brothers Brick, Alice Finch's Lego Hogwarts debuted last year at BrickCon, but it's just been unveiled online in a breathtaking 75-photo gallery, complete with scene recreations from the Harry Potter series. As you can see in the photo above, the scale of the project is massive; Finch says she spent 12 months over an 18 month period to build the structure, using about 400,000 bricks in all. "I do not know how much it costs and I don't really want to know," Finch says. "I have ordered most of the tan [bricks] by the box, and many other parts by the hundreds or thousands from all over the world."
