Washington, DC - Four pillars and a pattern

I liked how the designers of this labyrinth didn't let structural constraints get too in the way. They could have made a much smaller pattern but instead, someone decided to incorporate what was there and couldn't be moved into it. The result is a fairly long walk in fairly small space. This is on the patio level at Georgetown University Hospital on the Georgetown campus in Washington, DC. It's a very busy place but when I visited, the labyrinth was entirely unoccupied so I was able to take my time walking it. It was installed less than a decade ago.
