Golden Oak Library

The Golden Oak Library is a stocky hollowed-out tree and the home of Twilight Sparkle, Spike, and Owlowiscious in seasons one through four. In Twilight's Kingdom - Part 2, the aboveground portion of it is destroyed by Tirek, and Princess Twilight subsequently gains the Castle of Friendship. The library's main reading room is on the ground floor, while the bedroom is on the second floor. There is also a basement where Twilight performs her measurements on Pinkie Pie in Feeling Pinkie Keen. It is called the Golden Oak Library in Castle Sweet Castle, (the) Golden Oaks Library or Golden Eagle Library in some merchandise, Books and Branches Library at a former Hub website, and Twilight's Library in Gameloft's mobile game. Golden Oaks Library is now the home of the Ninjago Team, the Chima heroes and the Dipper Clones.
