Most of Fairlington was built in the mid and late 1940's to support the explosion of activity around the Pentagon during World War 2. But what did Fairlington look like back when it was brand new? You might be surprised. Today one of the most remarkable features of Fairlington is the "urban forest" with so many large well-established trees and groves of trees. But that wasn't the case in 1946. In the photo above one can spot a few spindly saplings staked up so they don't fall. Today those are mighty trees.
