You cannot get very close to the palace and their are no tours. This is one of the better angles you can get on the building. There is a guarded gate that keeps you ne'er do wells at bay. I used part of the pic below as the header to my blogue
To the right of the bridge, I believe, is the entryway onto the grounds that lead up to the palace
With a limited 4X magnification on my camera, I could not peer into any of the windows to see whats going on inside
