The BIG Maze, a temporary installation at the National Building Museum in 2014, inverted the idea of the traditional Renaissance maze: Instead of getting more bewildering as you advanced toward the goal, it got easier.

“From outside, the maze’s cube-like form hides the final reveal behind its 18-foot-tall walls,” explained Danish architect Bjarke Ingels. “On the inside, the walls slowly descend towards the center, which concludes with a grand reveal — a 360-degree understanding of your path in and how to get out.”

Kids who wanted an overview could ride on their parents’ shoulders or go up to the building’s mezzanine in order to memorize the layout.
