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 Lord 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 onPinkie Pie in Feeling Pinkie Keen . It is called the Golden Oak Library in Castle Sweet Castle, (the) Golden Oaks Libraryor Golden Eagle Library in some merchandise, Books and Branches Library at a former Hub website, andTwilight's Library in Gameloft's mobile game.

The tree has a beehive hanging from a branch, a candlestick sign on the front door (sometimes an actual candlestick figure, depending on individual animation errors), a sign of an open book outside the door, and two balconies, one of which has a telescope.

According to Lauren Faust, the Golden Oak Library was originally called "The Tree of Knowing".

In When the Cold Breeze Blows Away, it is where Twilight Sparkle located that it would be have measurements and magic books
