In The Cutie Re-Mark - Part 2, the castle appears in an alternate timeline in pristine condition, serving as Nightmare Moon's castle home.

Spike retrieves the Inspiration Manifestation spell from a hidden trapped chamber in the castle's library in the episode of the same name.After Twilight and Spike's massages, Spike suggests that they take the scenic route back to the castle.

Other rooms and areas in the castle include the "Hall of Hooves"—a hallway lined with torch wall-mounts shaped like pony legs—a corridor lined with suits of pony armor, and a basement chamber that houses the aforementioned "Organ to the Outside". Twilight Sparkle and Spike travel the distance between the two locations in a short amount of time, riding in a flying chariot pulled by two Pegasus royal guards in Friendship is Magic, part 1.When asked about her bell ringing duties, Pinkie says she rang the school bell for five minutes by standing inside the bell and banging her head against it, after which she was told that was "good enough". On the other side of the wall, Applejack and Rainbow Dash see the tapestry moving and hear Fluttershy struggling under it. This places Canterlot roughly in the center of Equestria and the hub of the train network, which goes under the mountain.

Canterlot's cloud stadium is featured in Sweet and Elite during the Wonderbolts Derby, in Rarity Investigates! The game includes a brief presentation of the controls that will help you get started with your creation right away! She makes some adjustments to the Crystal Mirror from the first film to make it able to open at any time, as opposed to every thirty moons. Twilight suggests that she and her friends keep a collective journal so they can learn from each other and ponies who read it in the future might learn from them.In The Cutie Re-Mark - Part 1 and Part 2, each time Starlight Glimmer and Twilight alter the timeline, the castle disappears, but the Cutie Map remains due to its connection to the Tree of Harmony. Fluttershy is nervous about being in the forest so late in the day, mentioning that it is star spider season.
