This aerial view of The Pentagon is undated, but looks like an early-mid 60-'s view. At the very bottom of the photo, below the cloverleaf, is where Pentagon City is now located.
The helicoptor landing pad can be seen to the left of the West Face of the building- this is the area hit on the 9/11/01 attack. To the left of the landing pad, across Washington Boulevard, is South Post Fort Myer. The northern-most barracks seen here were the original wood WAC barracks built in the very early 40's, when The Pentagon was being built, and later these became  men's barracks for those in Headquarters Company. This was the last area graded for the expansion of Arlington Cemetery (now known as Section 60) and sadly, this is the area where casualties of Afghanistan and Iraq are being put to rest. There was a very large front page story on Section 60 in USAToday during the summer of 2007. Memorial Bridge can be seen spanning the Potomoc, and Georgetown is just above that. The Key Bridge, then Great Falls is just upstream a bit.
