Hogwarts Legacy Arthurs Treasure Map Guide

Exploring the historic halls of Hogwarts in Hogwarts Legacy reveals a wealth of hidden secrets and engaging side quests. One early adventure involves helping a fellow student named Arthur Plummly decipher a mysterious treasure map. This guide breaks down the exact steps required to solve the puzzle, locate the landmarks, and claim your reward.
Starting the Cache in the Castle Quest
To begin this quest, speak with Arthur Plummly near the Astronomy Wing outside the Charms classroom. He provides a handwritten parchment containing sketches of three distinct landmarks located around the school grounds. Your task is to track down these locations in sequential order to reveal the hidden stash.
Understanding the map visual cues is essential for quick progression through the castle hallways. If you want to check out other guides, visit for helpful gaming walkthroughs. Keep your eyes open for architectural details as you navigate toward the first landmark.
Locating the Rhinoceros Skeleton and Fountain
The first landmark drawn on Arthur map is a massive rhinoceros skeleton located inside the Astronomy Wing. Head down the nearby staircases until you spot the iconic display case housing the creature bones. Once you reach the skeleton, your quest tracker updates, directing you toward the second clue.
Next, proceed outside into the Transfiguration Courtyard to find the central stone fountain. Look closely at the fountain structure, which features a prominent dragon carving matching the sketch. Reaching this courtyard landmark confirms you are on the right track toward the final location.
Unlocking the Hidden Painting Secret
From the courtyard fountain, walk through the large doors leading into the North Hall and head up the staircase. Continue ascending until you encounter a prominent portrait depicting a snowy landscape and a cozy cottage. This artwork matches the third landmark drawn on Arthur treasure map.
To solve the puzzle, cast the Accio spell on the handle positioned at the top of the painting frame. The magical force pulls a hidden doorway open, revealing a secret chest hidden directly behind the canvas. Open the chest to retrieve the Authentic Historian Uniform cosmetic gear piece.
Completing the Quest and Claiming Rewards
After securing the treasure, return to Arthur Plummly near the Charms classroom to report your findings. Sharing the solution with him completes the Cache in the Castle side quest and awards extra experience points. Equipping your new uniform cosmetic adds a stylish historical flair to your young wizard appearance.
Taking time to complete these minor exploration quests helps players become familiar with the complex interior architecture of Hogwarts Castle. The detailed design of the school ensures that every hallway holds subtle clues for observant adventure seekers.
