You are facing an inset in the wall with a nude male statue.  If you turn to your right you are going to see a huge open door.  And to the right of the statue will be several steps.  You are going to go up those steps.  You are going to continue down a marble hallway.  Continue to move forward down the marble hallway.  And you are going to go all the way to the end of the hallway and stop right in front of some white blinds on the wall and to your right will be a column.  You are done.
