what is the exact difference between "black gates:gate of mordor" and "helms deep"? in the pictures is looks, that both are walls between mountains, the first looking constructed like baradur consisting dark stones and towers, and "helms deep" looks at the picture brighter and without towers... is it correct? are they constructed between mountains to protect the valley? or are they used as city walls? this will be difficulter to create.
the path of the seath looks like a cave in a mountain? correct?
sorry, but i never have seen the lord of the ring-episodes... :/
