Golden Oak Library

Golden Oaks Library is a large hollowed-out tree and the home of Twilight and Spike. The 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. The tree has a large 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, Golden Oaks Library was originally called "The Tree of Knowing".[1]

Episodes
In Friendship is Magic, part 1 Princess Celestia sends Twilight in Ponyville to supervise Summer Sun Celebration preparations. She was supposed to stay in the library during her stay in Ponyville. The library is protected from lightning by a magical lightning rod as revealed in Look Before You Sleep. During the thunderstorm, Twilight haves a slumber party with Applejack and Rarity and during the end of the episode, a tree falls in the bedroom through the window. In Swarm of the Century Twilight wakes up in the morning to find the library infested with parasprites. In Sonic Rainboom Rainbow Dash crashes into the library and knocks all the books from the shelves making Rarity, Twilight, Pinkie Pie and Applejack organize them again.

In times of difficulty, Twilight often turns to her vast library to find answers. For example, in The Cutie Pox, Twilight pulls out a book called Perplexing Pony Plagues to diagnose Apple Bloom's case of "Cutie Pox". When Twilight and Spike are searching for a way to eradicate the Pinkie Pie clones in Too Many Pinkie Pies, Spike discovers a horseshoe-shaped button hidden in the back of a bookshelf. Upon pressing it, a secret compartment containing the desired book is revealed. In The Crystal Empire - Part 1, Twilight magically rips the entire tree out of the ground, exposing its roots. In Magic Duel Trixie uses her magic to flip the library upside down and shake books from it to the ground to persuade Twilight to have a duel with her.
