No.
Spoiler space...
The area with the puzzle box in it is actually very close to the
enterance to the complex. Climb up the rocks on the left side in the
entry room and go through the door, disable the gaurd, presto
puzzlebox.
This reminds me a little of one of the dungeons in Daggerfall. I think it was
Shedungent. Anyway, it was the one where you had to speak to the queens
mother, who is mad. When you get in you walk forward and come to a door that
won't open without a passphrase. You would have to walk all the way around
which took ages and what you wanted was right on the other side of the
door...along with some liches as well.
Actually, it's pretty near where you entered the dungeon. (I had a hard time
finding it too...I practically explored the whole dungeon.) When you first
enter you go down some rough stairs to floor level. If you look up you'll
see a second level that you can reach by climbing a different set of
"stairs". Look around up there.
