For Part 6 of our 10-part anniversary series, we take a closer look at the secret room in the Royal Library. In the movies, we only see the library itself—such as the place where young Anna plays during Do You Want to Build a Snowman, or the charades scene in Frozen 2. 

However, there’s actually a secret room hidden within the library based on various novels.

So, what is this secret room for?

The secret room in the Royal Library, as described in several novels, is a hidden, windowless chamber filled with magical artifacts and ancient texts from around the world.

How was the secret room discovered?

The secret room was first discovered by Agnarr and Iduna in the novel Dangerous Secrets (2020), while they were searching for the book The Little Mermaid in the library. Iduna accidentally collided with a horse statue resembling the Water Nokk. The statue toppled over, triggering a hidden mechanism that revealed a secret passage behind a bookcase. Inside, they found a portrait of Agnarr’s mother and a map leading to the Valley of the Living Rock.

In Forest of Shadows (2019), Anna and Olaf rediscover the secret room while searching for a cure for the Blight affecting Arendelle. Anna notices a hidden mechanism behind a stone horse statue, which opens a passageway to the secret chamber. Inside, they find a large collection of magical books and artifacts, including titles like Scrolls of Trolls, Quests of Yore, and The Alchemist’s Almanac.

Most notably, Anna finds Secrets of the Magic Makers, a book containing legends, maps, and a glossary of mythical creatures—with handwritten notes from Queen Iduna, revealing her connection to the room. This book unintentionally unleashes chaos, deepening the mystery surrounding the secret chamber.

In Polar Nights (2022), Anna and Olaf return to the secret room in search of information about the draugr as Anna remembers having read about the creature in a book hidden within the chamber.

After searching through the room’s collection, they find a book titled Of Nightmares and Nixies. Flipping through its pages, Anna locates a section on draugrs and comes across a sketch of a decaying, ghostly figure in tattered clothing.

In the podcast Forces of Nature (2023), the secret room is mentioned one last time when Anna brings Disa there to research magic in hopes of helping her protect Sankershus from natural disasters. As they descend into the dark, cold, and hidden chamber, Anna lights candles to reveal shelves filled with rare magical books and artifacts from around the world. She encourages Disa to explore the collection, hoping it will offer the knowledge needed to better prepare for future threats.

And last, it was mentioned in Deleted Scenes ‘The Secret Rooms’ (Video: Source) as well. Elsa and Anna discover a secret room with magical texts and a journal about Elsa’s powers. They realize it belonged to their mother, Queen Iduna, and are shocked to learn she spoke the forbidden Northuldran language.

The only room in the Frozen movies that might be the secret room is where Agnarr finds the map of the Valley of the Living Rock in Frozen 1.

However, both Frozen 1: The Junior Novelization (2013) and Conceal, Don’t Feel (2019) identify this location simply as the library, with no mention of a secret room.

In contrast, Dangerous Secrets states that the secret room is where Agnarr and Iduna found the map, leading to speculation that the two rooms may be the same. Still, this connection remains unconfirmed.
