It does seem to me that the above picture is a trifle flashy for a place Sauron used to hide out while he was rebuilding his strength. It's quite creepy looking, but does it make sense as a place for someone trying to pass himself off as the Necromancer rather than the Dark Lord? This fairly shrieks "someone important (and not just a lesser Nazgul) lives here." I always tended to think of Dol Guldur as your basic medieval stronghold, plain, fortified, and rather unimpressive, but effective.
