Cair Andros

The Cair Andros fortress is on an island shaped a little like a ship and it has levels but very little difference in height. Then to get the fortress you must cross through a cunk of land across the river to the island fortress.
The Cair Andros map that EA made was pretty good but Cair Andros is a FORTRESS on an island in the middle of the greatest river in middle earth. One other thing was that Cair Andros fell to evil only once and that was during the 3rd age great battle
