The gates to Thranduil's kingdom(terrace)

You've come to the great gates of Thranduil's caves, its largest entrance. The gates stand on the side of a hill, inside which the caves begin. Here is where the most sorties of this battle have been fought. Many times have the orcs surged forth and assailed the gates, and many times the elves have fought them back. The black smoke hangs over the battle-site, obscuring details, yet you can see the blood-soaked hill amidst a sea of nameless corpses.
The only obvious exit is terrace.
