The photo below was taken in 2006. As you can see there is still a large hole in the ground: "Ground Zero " is still a construction zone. Two years later, in 2008, there is still not observable building construction on the site although the infrastructure, I'm sure, is in progress and WTC7 has been built north of the site.
A prior post on the day from an astrological perspective is here. It discusses it from the perspective of The Saturn Return (the WTC buildings were 28 years old at the time). Here is another Saturn Return examination for not only September 11, 2001 but also for the Berlin Wall.
