The Trolls' Cave

Bert, William, and Tom Troll all lived in this troll cave. However, it was abandoned after they were killed by Gandalf, who killed them with sunlight.

History
In An Unexpected Journey, the Trolls stayed in a hideout when it was light outside.

Later, members of Thorin's company came down. While inside, Gloin, Nori, and Bofur buried the treasure to get later, while Dwalin just stood guard.

Thorin found Orcrist and Glamdring swords of the old King of Gondor. At first, Thorin did not want the sword, but Gandalf told him he could not wish for a final blade. Thorin took the wizard's word for it. Meanwhile, Dwalin disgustingly looked at Gloin as he stated they were burying it for a "long-term deposit", but Thorin told the trio that it was time for them to get out of the foul place and move on. Later, Gandalf found the sword Sting and gave it to Bilbo. Outside of the Trolls' hideout, Bilbo was reluctant to take the sword, as he never used one before in his life.

It is also the place where Gandalf told Bilbo to keep the sword, as it may one day be in handy.

It was known to smell rotten.
