There's really nothing though, they're not even lit. The front and back guards had (and still have) torches. The doors are probably locked, being presumably cells like your own.

The guards are armed with cudgels, and except the wounded one, they have swords at their hip (the wounded one, of course, had his sword stolen). They also have daggers. However, now that you're in combat you're not bloody likely to get a hold of any of those weapons, and you'll provoke attacks of opportunity if you so much as try.
