On Monday, we posted our eleventh photo challenge to see how well you know Metro. I took photos of five station pylons. Here are the answers. How well did you do?

We got 39 guesses this week. 15 of you got all 5 correct. Great job!

Image 1: Federal Triangle.

The first image shows the Ariel Rios Building, where the entrance to Federal Triangle station is located. 34 of you got this one right. A few of you guessed Union Station, which also has an entrance beneath an arch, but Union Station doesn’t have columns above like those pictured here.

Image 2: Metro Center.

This is a picture of the old Woodward & Lothrop flagship department store at 11th and G downtown. One of the entrances to Metro Center is beneath this distinctive building, and 37 of you guessed correctly. A hint to the location is the W&L in the shield near the bottom of the picture.

Image 3: Rosslyn.

The third image proved to be a little harder. The building in the background is the 20-story Rosslyn Center building. Some of you correctly deduced that the building was too tall to be in DC, yet was served by the Blue, Orange, and Silver Lines, which narrows it to Rosslyn. 24 of you guessed this one.

Image 4: Mount Vernon Square.

The fourth image was the hardest. This is Mount Vernon Square, with the Walter Washington Convention Center in the background. This curved part of the building sits directly above the escalator shaft that goes into the subway station. Only 23 of you knew this one.

Image 5: Farragut North.

The final image depicts the glass atrium of the Washington Square building at Connecticut and L, above the center entrance to Farragut North. 27 people got the right answer.

Congratulations to the winners!

Next Monday, we’ll have 5 more photos for you to identify. Thanks for playing!
