How to Complete Cache in The Castle in Hogwarts Legacy

Shane Williams

This is a guide for the “Cache in The Castle” Side Quest in Hogwarts Legacy. It’ll navigate you through the necessary steps to finding all four landmarks.

Speak with Arthur to begin the Side Quest.

I should let Arthur know that I solved the secret of the treasure map.

How To Start Cache in The Castle in Hogwarts Legacy

Once you’ve completed the main story quest “Welcome To Hogsmeade” you’ll be able to speak with Arthur Plummly who can be found in The Astronomy Wing. After speaking with him, he’ll give you a treasure map that shows you three landmarks which are scattered throughout Hogwarts: Rhinoceros, Dragon Fountain, Fountain and a Door Finding these Landmarks will help you narrow down the location of Arthur’s Treasure.

Where To Find All The Landmarks

From where you’re located with Arthur in The Astronomy Wing, make your way down three floors until you reach the Defence Against the Dark Arts Tower to find the Rhinoceros, then head down another set of stairs and go outside to find the Dragon Fountain in the Transfiguration Courtyard.

(1 of 3) You can find the Rhinoceros in the Defence Against the Dark Arts Tower.

You’ll now want to head northwest and enter the North Hall, then go up the two sets of stairs to find a large painting. Here you’ll want to aim by holding DualSense-L2 on Playstation and Xbox-TriggerLeft on Xbox, then cast the Accio Spell on the top of the painting to reveal a secret door. Proceed into the room and open the chest to find the Authentic Historian’s Uniform. Return to Arthur and the quest will come to a close.
