Nice photos ame :)
Those statues were built by the Druedain, a strange race of men who live in the forest north of Minas Tirith (maybe we’ll see them in the next update).
During the Second Age, the Druedain lived in Dunharrow, but they were driven off by evil men (a hostile dundenling clan maybe?).
Now I really want to start exploring the new area, but the constant CTD are keeping me off… For now :p
