The Great Goblin's cavern was a place in Goblin-town under the Misty Mountains and the seat of the Great Goblin, ruler of Goblin-town. The cave was rather large standing about one hundred feet high and three hundred feet long. At its eastern side stood a large platform where sat the Great Goblin until his death in July of 2941. It had only two ways in or out and was located about five miles from the Front Porch and about thirty miles from Gollum's cave.
