Via Work Zone Cam.

Here’s a friendly reminder that the National Building Museum is constructing a really cool maze and it opens in ten days.

Via Work Zone Cam, you can see the maze’s progress. If you have an amazing memory, this may spoil actually traveling through the maze once it’s open, so click with caution.

The maze, designed by international architectural firm BIG-Bjarke Ingels Group, will be in the museum’s Great Hall until September 1. “From outside, the maze’s cube-like form hides the final reveal behind its 18-foot-tall walls,” the museum said in April. “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.” More information can be found here.
