Unless you’re an architect or engineer, the National Building Museum probably isn’t high on your list of places to visit in DC. But we think it should be! Our trips to the museum have proved it’s much cooler than its name would suggest.

Currently, the museum is hosting a mini-golf course designed and built by architects and contractors from around the DC area.

Learning about the different designs while we played 12 holes was a summer highlight. Let us take you through them:

#1 “Hopscotch” and #2 “Hole in 1s and 0s”

#3 “Ball on the Mall” and #4 “Always a Hole in One”

#5 “Canal Park” and #6 “Mulligans on the Mall”

#7 “Take Back the Streets” and #8 “Piranesi’s Half Pipe”

#9 “Daedalus’ Journey” and #10 “Confluence”

#11 “A Hole Lot of Events” and #12 “Wood & Irons”

At the end of the course, players could vote for their favorite hole with cash. We put our money on #10 “Confluence,” which was inspired by the topography of Washington, DC. The hole’s designers, from Skidmore, Owings, & Merrill, overlaid Pierre L’Enfant’s 1791 plan for DC and a recent satellite image of the city to create the hole’s form. The name “Confluence” refers to the junction of the Potomac and Anacostia rivers in the plan, which serve as a path for the golf ball.

After our round of mini-golf, we stopped by the exhibition LEGO Architecture: Towering Ambition, which features 15 models of buildings from around the world made entirely of LEGO bricks. Here are some of our favorites:

Frank Lloyd Wright’s Fallingwater (southwest Pennsylvania), Eero Saarinen’s Gateway Arch (St. Louis), and William L. Pereira & Associates’ Transamerica Pyramid (San Francisco)

Bertrand Goldberg & Associates’ Marina City (Chicago) and James Hoban’s White House (Washington, DC)

The tallest building in the world—Skidmore, Owings, & Merrill’s Burj Khalifa (Dubai)

Both of these exhibitions are on display until September 3. If you can’t make it to the museum by then, one of its upcoming attractions might pique your interest.

We’re excited about two photography exhibitions opening on September 30: Detroit is No Dry Bones by Camilo José Vergara and Detroit Disassembled by Andrew Moore. It’s funny how this seemingly boring museum is one of the ones we visit the most!
